What do you think about me being 100% convinced that muhammad the prophet of islam was the antichrist?
What made you come to this conclusion?
If you read the bible and the quran it becomes clear.
I'm not sure where you're getting that information from, but I don't think it's correct. In addition, it's very insulting to Muslim people. I don't think you should continue to say things like that.
It's okay though because I'm a tough man.
You're free to have any opinion that you want on religion, as that is meant to be explored until you find what you're comfortable with believing. However, you should try to be respectful of other's beliefs, and not say things that could lead to unnecessary conflict.
