If marriage itself is based on the fact that the majority of us are hard-wired a certain way is it not discrimminatory to those who are not wired that way?[/quote[
The institution arose for very specific anthropological reasons that you simply aren't going to be able to argue your way around. No one dreamed up marriage between men and women, it evolved and it evolved for particular reasons that have nothing to do with homosexuals.
Marriage itself I care less about then the fact that homosexual couples have substantially fewer legal protections in terms of custody of their children, adoption, inheritence, the ability to be considered "immediate family" if their partner is hospitalized. Isn't that discrimminatory? Why are heterosexual couples allowed this favored status?
Those issues can be addressed by a good lawyer in the form of a contract between the parties that offer far more protection to each than a marriage licence and an "I do" before a preacher or justice of the peace. The only thing that a homosexual couple can't get that heterosexual couples do get is the marriage tax on their income.
That is the slippery slope fallacy. It doesn't necessarily follow that one thing will lead to another and another until beastiality or child marriage becomes legal.
I asked you where you would draw the line. If you are going to grant special rights based on sexual preference for one group, how do you rationally deny the next.
And the slippery slope isn't necessarily a fallacy. When the court in Mass decreed that homosexuals could marry, a series of suits were filed on behalf of polygamists. You can't rationally call it a fallacy if action has already been taken that demonstrates the reality.
Once again, if you are going to grant special rights based on sexual preference, where would you draw the line and what rational reason would you give for where you would draw the line?
The definition of marriage has changed over the years. At one time bigomy was the norm. At one time child brides were the norm. The point is who is to say that the current model of one male/one female is the only feasible one?[/quote[
Always between a man or men and a woman or women. You are asking for special rights based on sexual preference. Where do you draw the line and what rational explanation do you give the next group who also wants special rights based on some preference whether it is sexual or something else?
