I'm an atheist so maybe I should just mind my own business!
The thing is "Christains" wouldn't "hate" anyone or wish anyone harm. They would respect anyone who believed in and (albeit in their own way) worshipped God. Unfortunately, we live in a world where many people accept that a person is a "Christian" or a "Muslim" just because that's what they call themselves. There are "Christains" who post here who know less about the Bible and their own religion than I do and who seem filled with hate. They are happy to condemn other people (for example Muslims and atheists) and other religions (for example Islam) without knowing anything at all about them.
People who kill and maim "in the name of Islam" are not Muslims they are terrorists; people who preach ignorance, intollerence and hatred are not "Christians", they are ignorant biggots. The media, at least in the UK (and I guess more so in the US) are anti-Islam and, of course, anything that's on TV, in the newspaper or on the Internet just HAS to be right. It used to be black people or gays that were "hated", now it's Muslins.
Don't make the mistake of thinking it's everyone though. It's not. It's a small, loud-mouthed minority.
As an atheist I have to say I think Islam is one of the sillier religions, but, for what it's worth, I respect Muhammad (and Jesus and other prophets) and I certainly respect anyone with sincerely held religious beliefs. I also respect those beliefs providing they aren't used to hurt others.
So far, you have a mix of answers. Conentrate on the other easonable ones and remember some will be from kids who know nothing but are just repeating what they've heard equally-ignorant adults say.
