Don’t hate the man. We have a duty to love and pray for those whom wish to do us harm. That is not, of course, to say that we do not also have a duty to resist when such a person works to do harm... but we do so without hate in our hearts. Leave hate to those who insist on hating Americans.
With that said, you are dead-on correct about the Koran. Islam has never taught its adherents to “love thy neighbor.” More to the point: the teaching is actually unique to Christianity. The religion which comes closest to teaching this is Buddhism, but Buddhism teaches a disinterested “compassion” for all living things, which is actually quite different from the personal and involved love that is required of Christians.
The Koran itself teaches that Muslims have a social responsibility to one’s Muslim neighbors. Such is not based in “love” but rather in duty. Islam teaches that this duty does not extend to non-Muslims. Islam also teaches that unless non-Muslims are subjugated and in dhimmitude, they are oppressors of Islam which must be fought in secret and, when power allows, in the open.
This nonsense that all religions, at their heart, are the same is rooted in damned ignorance. I don’t say, “damned” flippantly but, rather, in much the same sense as C.S. Lewis once did - these attitudes damn us both in this life and in the life to come.
Christian love isn’t supposed to be limited to one’s neighbors, is it?
“You have heard that it has been said, You shall love your neighbor, and hate your enemy. But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you.” Matthew 5:43-44
