To answer your first question john, muslims dont believe that Prophet Muhammad (PBUH) is greater then jesus, i dont know who told you that.
And so you take a look at bad examples of muslims and take them as example of islam? riiight, i taught it best to look at the good of people not bad John, Im pretty sure christianity has a dark history as well, should i take bad examples of christians and say they represent Christianity? no john you dont do that. you claim you know alot about islam, but clearly you dont.
So the basis of this post is to answer why prophet Muhammad (PBUH) couldnt be greater then Jesus? hmm well i dont know know where u get your information from, but we dont believe any prophet is greater than the other.
And by you using allegations and using anti-islam language helps this topic how?
