Just as people tend to pull out the slippery slope argument, I do think people tend to claim that others are bigoted way too often and usually without merit. Now, let's be clear, will you find someone at that school that's definitely bigoted against transgendered individuals? Sure. I'm not trying to state that they
don't exist, but rather that claims of bigotry tend to be far too blanketed to be legit. To be bigoted against this girl, they'd have to be acting simply because of her transgendered state.
Now, I know what you're going to say... "But aikouka, they
are doing it because she's transgendered!" I don't believe that's the case, and that's not what these other posters are suggesting. At least from what I've gathered reading this, the issue is that when this girl is in the locker room, you're seeing someone who's mentally a female and physically a male. It isn't the combination (i.e. being a pre-op/hormonal transgender) that they have an issue with, it's that there's someone that's physically a male.
Do I wish this girl could find more acceptance? Of course. Do I blame any of the other girls for not wanting to see someone that has the physical aspects of a male in their bathroom? I don't think I can blame them for that. Although, I'm not sure if most guys would complain about the reverse.
