It’s offensive to people who have actually experienced genocide to use that word.
I’m happy you have no experience with war but if you ever do you will understand don’t stay in a war zone. Also if your government starts a war they better win it or you will have a bad time. There are multiple conflicts around the world right now but the one with a certain group people have a history of hating now is the focus of this hyperbolic language.
Again that’s just factually incorrect. War is tough. This isn’t genocide buddy.
