Most Muslims disrespect others' cultures but they don't overreact. Almost every Christian knocks wood and does his prayers when he hears "Satan, Devil, Hell, 666, Anti-Christ, etc...". And a lot of Christians think that every rule in the bible (no gay marriage for example) should be implemented. Also a Christian can become an extremist, easily. In my country, Greece, there is a political nazi party named "The Golden Dawn" who blame all the foreigners for our bad economy. What they mean by foreigners are the people who don't come from Orthodox countries (Russia, Serbia...).
Remember: It's only the nazis and the ones who overreact that I hate.
