Are you telling me that you think some people are biologically predisposed towards homophobia?

Just because people have the right to exercise free speech does not indemnify them from the consequences. Drawing broad strokes about how we should respect people's rights to express opinions while not judging them for those opinions is not practical. It's all shades of gray.
