I'm still waiting for an argument for the go what you are born as people that isn't masked bigotry. I'm sorry if this exposes some discomfort in the thoughts of some but this is no different than when white people tried to find reason for separate water fountains. It's dehumanizing and if one can't see that, wear the shoe, it fits well.
in some cases it likely is bigotry, but it's silly to insist that it all is or that it must be. just a few posts back you can see that catastrophe's thoughts were based in misconception - he was imagining externally visually males marching into women's restrooms and making everyone uncomfortable. he quite reasonably, imo, thought that hypothetical situation would be an unnecessary imposition on societal function. that's ignorance, not bigotry.
btw, the separate but equal comparison line is asinine. separate men's and women's bathrooms are by definition separate.
