On a philosophical level, getting bogged down in the genetics debate will get us absolutely nowhere. Is homosexuality genetic? I believe it to be, but until someone proves (or disproves) it definitively the argument is a dead end. For now, who cares?
That conversation is fruitless because it’s simply hair-splitting about how we got here. I’m far more interested in the fact that we ARE here…and now that we are, what everyone is going to do about it. Let’s try to stay grounded in reality here.
