Jesus was one of the greatest teachers in human history. His message of the golden rule is the same as other greats like Buddha, Socrates, Gandhi, Martin Luther King Jr. To live by the golden rule (or an identical ethical principle) is the only way to exist with a pure conscience, knowing that you have harmed no one and lived peacefully. This message was a great gift and example to humanity.
So, the question arises... Why, when teaching a message that stands alone as great and good, would one cheapen and ruin it with supernatural stories and the whole Jesus IS God element?
Jesus as a man teaches others that it is important to look at one's own behavior and be a responsible and good person. He was a great example of that since he lived by his own teachings. Once we attribute that ability to live the golden rule in the face of adversity to literally being a god, then how could anyone expect to follow that example. It makes being like Jesus something that we should give up striving for since it is clearly impossible if it took a God to do it! So what Jesus as god is really doing is letting people wallow in their curelty and hatred toward others since they know they are not able to live up to the golden rule, so why try. Besides, people are "Born into Sin" so they are made evil and may as well do what we are made to do. Instead of teaching that one should be like Jesus, people believe that Jesus "died for everyone's sins" so they wouldn't have to be like him. What happened here!? All the meaning and message of Jesus the human now destroyed for Jesus the "god."
Those who believe in Christ's message as a teacher, see the good in his message and try to emulate that. Those who believe in Jesus as a god and "dying for our sins" see that as a ticket to commit wanton acts of brutality and evil, as long as they believe that someone already took care of their sins.
It is therefore no suprize when one looks at the people in this country that call for assasinations, wage war, fuel the fires of hatred against their fellow humans, and gleefully destroy the planet with no regard for life, and still call themsleves Christians. They even think they are getting a heaven after their lives of evil! These are some of the sickest individuals on the planet, yet, because they took the humanity out of Jesus, they feel free to disregard his message yet at the same time claim to believe in him.
Not all christians are like that of course, but you know the type I talk about. The ones that are greedy, selfish, decietful, hate filled, embittered toward the world, and despise humanity. They don't believe in Jesus, but believe in the vengeful and spiteful god that they wrongly claim Jesus to be.
That license to remove Jesus's message from Christianity by replacing him with "god" is the evil of Christianity.
