I and I'm probably speaking for a fair number of non-theists, do not 'hate' Jesus, if anything and assuming Jesus actually ever existed (as described in the bible), I respect his ideology and wish that everybody could be Jesus.
Alas, Jesus was hijacked by emperors and kings and 'the church', and his ideology was and is used as a political weapon and for dubious reasons, against all manner of people. As you say, most 'Christians' wouldn't recognise Jesus if he did cartwheels on water in front of their very eyes, and neither would most of the clergy, Christian prime ministers, presidents and kings.
Most people that profess to be Christians are ignorant hypocritic shysters that praise Jesus because they think that by simply 'believing', or saying the odd prayer, or making the sign of the cross at apt moments, they will be saved from hell. These people are no more than selfish cowards that will do the most horrendously unchristian things at a moments notice without remorse or even any awareness of their 'sin', happy in the knowledge that by going to church, singing a hymn and saying amen they have guaranteed themselves a place in 'heaven'.
