People of a certain race don't follow a common book telling them to be criminals though so it doesn't really relate. As for interpretation, I see that excuse all the time and I have read the bible. The way I see it, it's explicitly written down and in order to not be taken at flat out face value, you have to interpret it away. So for me, I just can't buy that. You're cool with it and don't get me wrong, I'm glad there are a lot of accepting Christians who can interpret that away, but at face value, I'm not happy with that excuse and can't personally buy into it. Especially when knowing the interpretation is not something followed by all. Again, I'm just giving you an honest view from a non-theist. I can't trust someone devout to a religion based on an anti-LGBT book to be accepting until they prove themselves to be.
Yes, you can argue that non-theists can be non-accepting, but the truth of the matter is that for the vast majority this just isn't true. They typically aren't influenced by any specific anti-LGBT books and so I don't see a red flag, I see more of a pale pink verging on white (white being that which would indicate accepting/safe). There's a hint of red in there still because it's not a definite but the liklihood is far, far lower.
I'm not saying it's okay to bash on the religious, I'm just giving you an honest view as to why people are anti-Christian until they prove themselves otherwise. IMO the burden is on the religious to prove themselves worthy and not on the rest of us to assume they're okay, and especially true in the LGBT community. In my everyday life, as stealth, I will full on admit that I'm wary and cautious around the religious and often try to feel them out in some way shape or form to find out if they are LGBT accepting because I don't want to make friends with people who will bash me or out me to all if they somehow found out. And if I can't feel them out, I just flat out decide it's not worth the risk. There's someone I recently found out is mormon, and that was it, I wanted nothing to do with them and turns out I was right in doing so.
I'm not trying to justify any hatred towards the religious and if you're religious that's all well and good. It doesn't affect my life (assuming people just keep the damn thing out of politics) but I'm just giving you an honest view. For a lot of people, especially in the LGBT community, religious = red flag and I honestly never see that changing. Feel free to defend your own branch of faith but you can't defend Christianity as a whole because it is a split with regards to acceptance. Some are fundamentalist and some aren't and it's not like you have a clear defining name for accepting side and non-accepting, the term Christian applies across the board.
