Because this is a good thing, and needed to be shared more.
Oh, I agree wholeheartedly. The problem is, I'm not in the majority.
Many people try to use their faith as a justification of their prejudices, and this article calls them all on it in language that no christian can easily dismiss. Since christianity is a majority religion in the US, disseminating this is a good way to slap a lot of people in the face and possibly get them to think.
Less cynically, I don't think faith has to mean that. And I don't think it means that for the person who wrote this.
I don't really care what their justification is for their opinion, just the opinion itself, as long as holding a particular opinion is not compelled by the state.
I think beating gay people into bloody pulps is a worse evil than blind faith and obedience to texts written thousands of years ago by middle eastern sheep herders.
And I don't think there's anything in that text that allows the majority to assume that squelching dissenting opinions is OK. To me, it's more like speaking the language of the person you're trying to convince. Unless you just want to kill your opponent, it's important to try to negotiate with them in a language they understand and will not dismiss out-of-hand.
