Then you're just not thinking clearly. The reason no distiction is being made between "good muslims" and "bad muslims" is that they are both followers of Islam, and it is Islam itself which is the problem. It isn't the "bad muslim" that is the problem, it is the "good" one that actually follows the teachings of his religion, a religion that calls for the abolition of secular government in favor of an oppressive islamic regime under Sharia rule, and a religion that demands of its followers to "kill the infidel wherever you find him".
I see no 'wink wink...look how funny I am with my joke about Muslims'. Deep in many peoples hearts is a true and honest hatred of Muslims
You do not understand. It is not Muslims we hate; it is Islam (Muslims are only victims of its "success"). And the reason we hate Islam is because it demands that we surrender to it; giving up essential freedom while adopting rules of behavior completely incompatible with enlightened civilization.
Do they know any? No
You're projecting. In truth, all the people I know who have experienced the face of Islam first-hand are those who are most opposed to it. Only those ignorant of the teachings of Islam, like yourself (unless you are a Muslim practicing al-taqiyah; there have been more than a few on this site), find anything positive within its beliefs.
Perhaps you are simply someone who has a few Muslim friends, who you think are "nice guys". And since they seem nice, they couldn't possibly be like those "other muslims", who must be an exception to the rule. The problem with your thought processes are two-fold. First, you are thinking via argumentum ad ignorantiam (you don't really know what Islam teaches), and second, you don't really have any way to know the true motives of your Muslim "friends". The people who "knew" Capt. Yee were confident that he was a loyal American and their good friend as well.
