I wouldn’t particularly care since I’m for individual rights that do not depend on immutable characteristics much less ones that people could surgically alter. I identify much more so as an American or a classical liberal than I do as white.

Racial reassignment? Really?
That's the most ridiculous thing I've heard today. It is, however, still early.
I understand "gender reassignment", because sometimes, nature gets it wrong.
Racial reassignment is straight-up stupid.

I don't see a problem with it. It personally seems a bit pointless, but these things aren't about how it seems to me. If it's important to somebody else, then it's important, and not something anybody else should be worrying about.

I find the entire "identity reassignment" movement laughable.
