How I got to that conclusion to was by reading up on religions and reading the texts like the bible. The bible is actually quite interesting and there are some very good ideas in it. But most practitioners of their religion pick and choose bits or want to stick in their head in the sand about the fact the Jewish, Christian and Muslim religions are so similar and all three borrow bits from previous religions. Where as the wise thing would be to say there reason for all the similarities are that the fundamentals are true and they've just come out differently due to human interpretation and therefore embrace the other religions rather than act as if they are your worst enemy.
While I agree that these three (and all) religions shouldn't make each other their worst enemies, to claim that they are all the same is silly (this may not be your intent). Obviously all worship the God of Abraham, but each have writings that theirs is the only correct way to worship him (for example, John 14:6). Thus, your ideals of 'reading and following the complete holy text' and 'buddy up with the other religions' are somewhat at odds.
It's not that hard to see that America's "Christian" right and their beliefs do not match Jesus' teachings and beliefs. For starters the bible is quite clear that you shouldn't be a loud mouth religious jerk and that your connection to the lord should be private.
Slight clarification here. While one's relationship to God is meant to be private (the teaching is to pray, give to charity, and to fast in private so it doesn't become a status symbol or lead to boasting), it does not apply to teachings. It teaches we should preach the gospel loudly, but also to admonish those who need correction in private. More applicable here is 1 Corinthians 5, particularly 5:12 "What business is it of mine to judge those outside the church? Are you not to judge those inside?"
I'd go out of my way to help out someone who truly followed the word of Christ. I think for someone to sit down and actually read the bible and do their best to follow it to the letter is very admirable. By that I mean the important bits about helping your fellow man and not being a greedy douche. But there in lies the problem, I've not really met anyone like that and I've certainly not seen them on TV.
I think the problem is that they exist, yet are frequently busy helping and are absorbed within the Church rather than going out and meeting those outside. Or, the people they are meeting are elsewhere (I am connected with churches performing missionary and relief work in Mexico, Thailand, China, areas devastated by hurricane Katrina, local school districts, and multiple Indian reservations). In addition, many of this long-distance work is selflessly financed by the ones traveling, and those involved often return because they can't stand the suffering these people experience. Trust me when I say that these people exist, and they truly care about both Christ and others. The trick is to find a church where God truly is the center of all that is done (several of the churches I have attended), rather than focused on themselves (unfortunately, the church that I grew up in had a large number focused on this).
I certainly agree, though, that Christians should be seen by the world for the good they do, yet rarely are because the good they do is either less visible or nonexistant, or they instead do evil.
It's easy for people to say that Muslims need to tackle their extremists (which they should) but Christians have the same exact problem and they need to start standing up and condemning those who don't follow the bible properly rather than paying Sarah Palin to read a speech off her hand.
Again, big agreement from me. For the record, Pat Robertson and the Westboro Baptist Church do not speak for my God.
