Genocide is the systematic extermination of a people, not because of what they’ve done, but because of who they are. When Muhammad ordered the Jews of Banu Qurayza to be lined up, and slaughtered 700 of them in a single night, that was genocide. When ISIS stormed into Yazidi and Christian villages in Iraq, massacred men, enslaved women, and turned girls into sex slaves, that was genocide. When the Nazis rounded up Jews, forced them into gas chambers, and burned their bodies, that was genocide. The common denominator in every genocide is that the victims were slaughtered not for anything they did, but because their existence was unacceptable to their oppressors. When Hamas terrorists stormed into Israeli villages, slaughtering 1,200 people, men, women, children, elderly, burning families alive, beheading babies, raping and butchering women, shooting civilians in their beds, that was a Genocide. They hunted civilians down, house by house. They went into bomb shelters not to escape bombs, but to execute families hiding inside. When Israel fights back, when it retaliates to eliminate the same terrorists who committed genocide, when it fights to rescue hostages, when it takes military action against a terror group that hides behind civilians, that was not a genocide. Genocide is what Hamas did on October 7. War is what Israel is doing to stop Hamas from doing it again. Those who have been marching in the streets, screaming “genocide” are nothing more than blind followers who have no idea what they’re saying. They chant slogans fed to them by terrorists, acting as puppets in a propaganda war they don’t even understand.

@VKazulkin Thanks for sharing my story!

"A Team Leader’s Conviction: Bringing AI to a Team of Skeptics." This new reality reshaped our team. Used right, AI doesn’t replace great engineers — it supercharges them. by @schuftan medium.com/wix-engineerin…

AI did a week-long refactor in days. 100+ files changed. Code worked, but who maintains it at 3AM when it breaks? "The AI Code Velocity Trap" - mistaking speed for productivity. Read more: medium.com/wix-engineerin… #AI #DevTools

My team and I have been working on bringing AI into our workflows - but here’s the twist: we also own CI/CD for Wix Mobile. And CI/CD is all about predictability. So… how do you mix that with AI? I wrote about the challenge - and what surprised us: medium.com/wix-engineerin…

🤯 Just dropped some AI magic into Detox, and it's NEXT LEVEL! Oh, and guess what? It's also OPEN SOURCE! 🚀👇

Noa Argamani (25), Almog Meir Jan (21), Andrey Kozlov (27), and Shlomi Ziv (40) were rescued in a special operation by the IDF, ISA and Israel Police from 2 separate locations in the heart of Nuseirat after being kidnapped by Hamas from the Nova music festival. This is what Israel is fighting for! Welcome home ❤️🇮🇱🙏🏼 We will not stop until all hostages are safe and sound back in Israel. #broughtthemback

Two new pieces of evidence prove #Hamas responsible for #RafahOnFıre incident, as posted here yesterday: 1. incriminating conversation between two Gazans 2. satellite images of rocket launchers Both indicate a Hamas weapons warehouse, hidden inside the #Rafah camp, caused fire.

Must watch! The IDF drops a media bomb on the #UN: Armed #Hamas terrorists walk around and fire weapons inside #UNRWA's central logistics warehouse compound in #Rafah and near UN vehicles. Seriously incriminating evidence. I wonder what the UN's @antonioguterres has to say...

Must watch: A Palestinian describes his visit to the Auschwitz extermination camp: "God wiling you will return to the camp... you belong here." These ideas are common among Palestinians, and now we're seeing them in campuses across the US... #Antisemitism #FreePalestine

IMA SAY IT: #FreePalestine MOVEMENT IS HATED IN AMERICA. FLAT OUT HATED. We hate your protests. We hate your antics. We hate your tacit and open support of HAMAS, Hezbollah, Iran, Yemen & Al-Qaeda terrorists. We hate your TikTok driven ignorance & your ridiculous social media confession that you are just Jew haters. What we do love is Freedom of Speech and its the only reason you exist as a group. I look forward to your immediate departure for Gaza or arrest for being stupid & blocking a major arterial.

@Jack_Petocz You’re a useful idiot.

I'm Jack Petocz, a 19 y/o activist that's been fighting for marginalized people for years. Yesterday, I was expelled from Vanderbilt University for peacefully protesting the genocide in Palestine. Vanderbilt will let sexual assaulters walk free, but expel passionate organizers.

@TepperYoav מגניב מאוד מאוד

🚨 ברייקינג: הכל חרא! 🚨 אני (לא) גאה להשיק את דאשבורד ״חרדות ברזל״. כמו שמראים לנו כמה כפות סוכר יש בשתייה מתוקה כדי להדגיש היא מזיקה, ככה הפרויקט הזה מנסה להדגיש בציניות את הרעל שדוחפים לנו למוח דרך החדשות שעושה לכולנו נזקים. #פידטק

Israel having to negotiate for the release of its civilian hostages is among the most absurd and humiliating things I’ve ever seen in my life. These aren’t POWs being exchanged among warring nations after having been captured in battle. They’re KIDNAPPING VICTIMS, forcibly dragged from their homes at gunpoint and kept in underground rat tunnels for months. Yet Israel has to send delegations to Paris and kindly ask that the governments of Qatar and Egypt—those noted bastions of human rights!—intercede and convince Hamas terrorists to release them, in exchange for Israel releasing violent criminals (with a ratio that will undoubtedly be an order of magnitude greater, of course). As if civilian hostages and Hamas militants are morally fungible. Maybe I’m just a dumb Marine who doesn’t understand the world of diplomacy, but it feels like nothing less than a ritual in forced humiliation. Having to barter for the safe return of women and children. Rape victims and babies. It’s repugnant. Don’t get me wrong, I don’t blame Israel for doing anything its power to secure the safe return of its people. I respect them for seeking resolution using all the means at its disposal. God knows, I’d do nothing less in their situation. But Israel shouldn’t *have to*. Hamas releasing the civilian hostages it seized on October 7th should be a basic prerequisite for all other points of consideration here. Returning the hostages should *precede* negotiations for a ceasefire, not be used as a bargaining chip in exchange for one. Then again, what do I know? I’m just a random guy on Twitter who continues to be shocked at the utter moral cowardice evinced by so many public figures, global leaders, and political officials since October 7th. Surely, I’m missing something in my understanding of the situation. After all, there’s significant historical nuance here, and the dynamics are far more complex than terrorists simply having kidnapped, raped, and murdered innocent people. Right?

Every hostage must be released immediately and unconditionally. Bring them home now!
