Common but false comparison because of the propaganda in America and other Western countries where you are brainwashed to compare Islam to Christianity or some other religion, instead of realizing the real battle is between Secularism and Islam.
At the forefront of this foolishness are the so called liberals who would blast a christian for being a bigoted homophobe if they are against gay marriage and consider a cross in urine as art and burning the bible to be free speech,
yet at the same time defend (apologize) Islam due to their multiculturalism brainwashing and they consider burning the Qur'an as hate speech, and call those who criticize Islam bigots or Islamophobes, and of course their oldie but goodie "but the christian did it too."
Ataturk had it right, but thanks to the Saudi's and the apologetic west love of oil which help finance the Wahhabi madrassas Islam has gone a different way.
Let me help you out here. Being against America legalizing gay marriage is at its heart bigoted because it goes against the entire concept of equality in this nation, but that doesn't mean you aren't free to be against it and that vocalizing your opposition is disallowed from your free speech rights. Pissing on a cross or burning a Bible is free speech, that doesn't mean it's not hateful or in the case of the peeing on a cross pointless and stupid.
As far as defending Islam, no one is defending those who commit terrorist acts. However, when a religion has over a billion followers and a few hundred or even thousand are terrorists, that doesn't make up the viewpoint of the religion as a whole. Also, trying to have a war against an entire religion is just insane and trying to paint the entire religion as evil is a losing proposition, we need to be inclusive instead of exclusive.
Also, yes there is quite a bit less Christianity inspired terrorism than Islamic. That doesn't mean that Christianity is without faults of its own.
Really, the war is secularism against ALL religions. Because secularism is the only right answer. Reason should always win out over faith.
