Trying to paint homosexuals as Nazis just because some Nazis were homosexuals is as ridiculous and deceitful as calling all white southerners KKK members just because some members of the KKK were white and from the south. Your attempts to do so are only destroying your credibility and harming your cause.

I am not defending homosexual marriage, I am discussing the most probable future result of current trends. For the record, IMO pursuing a Constitutional Amendment defining marriage is a waste of time and political capital.
