Another one ; the word "apologist", as it applies to political causes or historical regimes. It's such a smug, self-righteous cunt of a word that implies that whoever disagrees with you already knows how wrong they are, and I've never seen anybody call anybody out on using it. But they should. Every single time somebody says something like "liberal apologist" (or any other X-apologist), somebody should point out that people who support liberal beliefs don't feel the need to apologise for liberalism. Otherwise they wouldn't be liberals in the first place, would they?
And before anyone points it out, yes, I know that etymology of the word means rationally defending a viewpoint, not apologising for it. I'm even willing to concede that some, or even most people who use the word also know that. But it still carries a very, very strong implication that anyone who disagrees with you secretly believes that you're right. And that makes me immediately think of bighead.
And that's terrible.
