isn't this literally just hating on a religion
like Allah wouldn't actually approve of killing somebody for absolutely no reason, just like God (Christianity or Judaism) wouldn't
Abrahamic religions believe the same God, they fight over who the delivery boy was

No. Islam says many times to kill unbelievers and Christians. It also says as long as you kill in the name of Allah its ok. It is nothing like the Christian or Jewish religions.

I've already read it. Did you know later passages in the Quran override older ones? The final passages say you can do whatever as long as it's in the name of Allah. You are also commanded to tax or kill Christians and unbelievers. Are you a bad Muslim?

as an atheist, the "kill nonbelievers" part was likely instructions to Muhammad.

Oh please.
Google it. I do hate Islam, and I don’t care at all what you think.
