All Muslims are evil - I don’t necessarily agree with that, but I can see why it is reasonable to believe that. I think it’s more reasonable to believe that Islam as an institution is evil, but that there are individual Muslims out there who are not evil.
All evil people are Muslims - That’s what you’re really trying to assert on this thread. I hope you can see the difference between that assertion and the first one that I posted. You are the one being naïve and you are the one who needs to watch your back if you truly believe this. There are plenty of evil non-Muslims out there in the world. It may well be that one of them just crashed a German plane into a mountain; why don’t we wait for more evidence to see whether or not that’s the case?
