Do You Believe Jesus, Or Not ???

Here is what I believe to be one of the key principles of Christianity:

Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine 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;
That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.

Matthew 5:43-45 KJV

And here is a report about people who did what Jesus told us to do:

Note how their actions are called "pure insanity", "the suicide of the West", etc.

To me this is the real tragedy of the so-called "war on terror" - we have stopped being Christian. We were put to the test, and we failed.

If you disagree, please show me ANYWHERE in the New Testament where it even suggests that we should not love our enemies.
