I think you'll agree with me that it is possible to disagree VEHEMENTLY with a person of another faith, on matters of doctrine, without dismissing--or even targetting--him as an "infidel" and his entire religion as "the enemy of mankind."
If you cannot behave in that way, then you are really no different than the "jihadists" who have brought such misery to this particular moment in time.
Respect of and tolerance for another's beliefs do not require you to accept them, or even understand them, or to discard your own deeply held beliefs. However, it DOES require that you coexist as harmoniously as possible in conformance to the precepts of civil society.
This nation was founded among other things upon the principle that one should be free to worship God as one chooses. That right presupposes that one can worship unmolested, without fear of becoming the target of outrage by those who don't share your beliefs.
Note that I'm not talking LAW here, I'm talking PRINCIPLE.
