Jesus didn't pretend to be an example for anything other than morality and spirituality.
it's a rather hollow argument, and a bit dishonest, to dismiss him on grounds other than what he specifically provided an example for.
I think it's completely fair to judge his morality when he showed, by his actions, that he was jobless, asked people to leave their families, to hate their parents, threatening people with Hell if they don't agree with him, condoning slavery - and beating slaves, etc.
Bertrand Russel said:
"There is one very serious defect to my mind in Christ's moral character, and that is that He believed in hell. I do not myself feel that any person who is really profoundly humane can believe in everlasting punishment. Christ certainly as depicted in the Gospels did believe in everlasting punishment, and one does find repeatedly a vindictive fury against those people who would not listen to His preaching—an attitude which is not uncommon with preachers, but which does somewhat detract from superlative excellence. You do not, for instance find that attitude in Socrates. You find him quite bland and urbane toward the people who would not listen to him; and it is, to my mind, far more worthy of a sage to take that line than to take the line of indignation."
It's fair to look at Hero's with a clear head.
Luke 14:26:
“If anyone comes to me and does not hate his father and mother, his wife and children, his brothers and sisters—yes, even his own life—he cannot be my disciple.”
Matthew 19:29:
“And everyone who has left houses or brothers or sisters or father or mother or wife or children or fields for my sake will receive a hundred times as much and will inherit eternal life.”
Revelation 2:22-23 (Because a starving woman ate some food meant to be burnt for sacrifice)
“22 Indeed I will cast her (Jezebel) into a sickbed, and those who commit adultery with her into great tribulation, unless they repent of their deeds.
23 I will kill her children with death, and all the churches shall know that I am He who searches the minds and hearts. And I will give to each one of you according to your works.”
Not to mention, the insanity that Christianity is a religion of human sacrifice, and that Substitutionary Atonement is a ridiculous idea.
If we executed someone other than the person who did the crime, we'd say a huge injustice had been done. Yet, Christians believe this is moral - even beautiful.
