The dinosaur thing was just an example to deal with the concept of burden of proof. So I suppose in a way I was trolling about it, or at least I didn't make it clear enough that it wasn't what I actually thought.
I do believe in science, and I haven't found that scientific discoveries conflicted with the Bible. Interpretations of the Bible do change over time, but the actual text in the Bible does not go out of style. Well, I guess translations do, but you know what I mean. The Bible says God created the planet in a week, and that includes all the plants and animals. We have evidence of evolution, but that doesn't necessarily invalidate the creation story. God is fully capable of kicking off, directing, and accelerating evolution so that it still fits within the allotted time.
I take issue with your line of reasoning in the gay marriage sentence, but to be clear, I'm not saying it should be illegal, just addressing the logic. Just to avoid misconceptions, let's apply the same reasoning to alcohol instead. Something being legalized has nothing to do with whether God accepts it. Yes, God ultimately has all authority, and yes, the Bible says to follow the laws of man, but the laws of man are ultimately the laws of man, and there's a clause that the laws of God take precedence in a conflict. But even if that weren't the case, if the laws of man say we're allowed to get drunk, that doesn't mean we have to. The Bible still says it's a sin (which I think is because it leads to unwise choices and other sins that you could blame on the alcohol,) and what mankind thinks doesn't change that.
Also, to be clear, since you think I'm a hardline kind of guy, something being a sin does not mean we have to fight to make the laws reflect that. There's a lot of talk in the Bible, especially in the new testament, about how the laws are not enough to make someone righteous, and that was the whole point of Jesus. I do take hardline stances in that what the Bible says is true, but I'm not going to condemn people around me for working on the sabbath, and I'm certainly not going to try to make it illegal. (Well, a law against employers requiring you to work 7 days a week would be good on its own merit, but it doesn't have to line up with the sabbath.) Another biblical principle is that the way to reach someone is by love, not force.
