You can have beliefs. But most religions are actively anti-LGBT, so you are in a bit of a pickle here. Associating yourself with an intolerant group is going to attract hostility for people who fight intolerance. And the paradoxical situation you seem to be here leaves you on the wrong side of both sides.
If your beliefs are proper beliefs (and not weird crap from religions) no atheist can ever have an argument against that.
As far as we are from the death of art I guess.
