It doesn't really matter what the insult may or may not be. If you go through life thinking everyone is going to be nice to you, HEH...I got news for you. I don't see how it makes someone a non-believer by not getting offended by insults to your religion? Humility is part of life.
If people think they can live their life without insult, go on 9gag or reddit. Or any forum- Hell, go on THIS forum. See how long that lasts.
