Not sure you guys are aware of this, but theologians have actually thought about how to apply- or not apply- rules from the Bible to today. A common understanding is that the Old Testament laws (ie Exodus and Leviticus) contain both "moral laws" and "ceremonial laws". The moral laws are rules that should apply to all people at all times, such as the ten commandments (though shalt not kill, steal, commit adultery and so on). The ceremonial laws (ie mixed fibes in clothes) applied specifically to the theocratic kingdom of Isreal at that time... the New Testament explicitly states that Christians are no longer obliged to follow the ceremonial laws.
Of course there's a lot of debate about which "rules" are ceremonial and which are moral, homosexuality being a key example that is much debated in the church today. And of course there is a ton of good old fashioned hypocrisy among Christians as well... just wanted to point out that there's a bit more going on than just random picking and choosing of Bible laws.
Bonne, I also don't udnerstand how so many Christians can be so selfish and hateful and greedy... it sickens me, and it worries me because I don't want to be one of them. And I'm glad you agree that the Bible does have a lot of good things to say.
