You are not getting the point, or are deliberately ignoring it.
I did not make a statement as to "proclaim" the non-prophethood of Mohammed, my point was to remind you that the same way as you look at our Apostles, we also think the same of your apostle or porphet, whichever word you like to use.
I don't think we have to choose between Paul or Jesus, do you have any reason why we should choose between the two? According to Muslims Paul is our founder, that should raise him to an even higher status, don't you think?
If Paul is a prophet to us, why should we allow you to offend our prophet, and yet not be allowed to offend your own prophet? Is that too difficult to understand?
Personally, I don't believe in do unto others as they do unto you, but I don't think that anyone should complain, if there should be someone doing in return as Muslims do with Paul.
