I used to think that by the 30th gender I've read about, it was starting to get ridiculous, but then I thought, but why should I care? If a person wants to identify as two spirited rather than bi-gendered, why should I care? How would that even conceivably affect me?

It doesn't. Trans people don't bother anyone else. They ask for the most basic acceptance, and that's it.

As a genderfluid person, I'm asking even less of society, and I'm not getting it :/
