Your reasons for keeping marriage male/female are valid even if they aren't verbose. You don't have to engage every argument, especially if those arguments are made by rude or obnoxious people.You don't really make any arguments, Brian. You simply slap together some bumper sticker slogans and post them here. When asked to give supporting evidence, actual argument, for them you avoid responding.
There is no gender equality right in the Constitution; marriage has always been male/female.
