It’s become shorthand for saying “Ideas that I happen to find ridiculous are being taken seriously by a lot of people, and it’s ruining this country,”
which makes its definition entirely subjective – and therefore
arbitrary. For example, a person who’s all for same-sex marriage might
scoff at gender-neutral restrooms as political correctness gone too far.
Because apparently, political correctness only goes “too far”
when it applies to the unfamiliar, the not-often-talked about, the
marginal, the stigmatized.
