I'm not going to lie and say I don't dislike fundamentalists, but I hate the so-called "liberal christian myth." The problem with these people is they actually nit-pick the parts of christianity they don't like. An example of this is their support for the notion that homosexuality is natural and alright, despite it being said in both the Old and New Testament that homosexuality is an abomination. What these people don't understand is that religion isn't something that can be compromised upon.
Another interesting thing is some "liberal-christians" being against capital punishment. Some justify this by Jesus stopping a gaggle of people from stoning an adulterous woman. What they don't realize is in this case Jesus was stopping hypocrisy. These men were all as guilty as the women when it came to infidelity and hedonistic lust. When Jesus said "Let he who is without Sin cast the first stone." He was using a paradox to say it was not their place to put this women to death: because they were duly guilty of the crime. Infact, I interpret this as Jesus being for execution because he didn't say "Do not cast the first stone, for this a punishment only for God, thy lord to decide."
The difference between fundamentalists and new-age christians is that fundamentalists are actually true to the religion. I won't go as far to say liberals can't be christians at the same time, but I believe the most they are is quasi-christians. Choosing which parts of the religion they do not like and disregarding it.
