3run:
The image series "Jusus vs. Mohammad" is basically stupid, yes. They compare 2 religions and claim that their own one is better. This is just like when 2 kids are telling each other that their dad is stronger and better than the other one.

This is simple thinking.

But at the same time the Jesus image as a body builder is funny and creative. I can smile about it even if the background is a bit dumb.
I see no reason to get upset because something of that.

Maybe these people do not respect you enough, because they do not know you enough. As you said, they dont know your religion. Many even dont know that it is not allowed to draw people. This can happen and is not a bad thing.
Dont make it up too much.

I am sure that most of them are fine guys and will respect you, when you meet them at the street.
