Hating on Islam is completely acceptable, just as showing dislike towards any other undemocratic way of life.
Hating on Christianity is completely acceptable, just as showing dislike towards any other undemocratic way of life. [/sarcasm]
Islam is not an "undemocratic way of life". It's a religion. Just as it is with Christians, Buddhists, Jews etc., Muslims can be democratic or antidemocratic. Saying Islam is an "undemocratic way of life" is like saying Christianity is homophobic. True, there are many Christian idiots who hate gays. But there are also many tolerant Christians that let other people live the way they want.
