Yeah, I agree. Sure, I can imagine scenarios where these terms can be useful for thoughtful discussion, but I'd also say that I get the impression that a lot of the social justice stuff I've seen comes from people who are very sheltered, perhaps because they are very young. As annoying as it is now, I can only hope that these examples will be a source of embarrassment for those people for decades to come. Another problem with this kind of language is its insular and exclusive language, as in, "everyone who doesn't use or acknowledge these terms are therefore part of the problem", which is demonstrably bullshit. I also think that it promotes the idea that people should be vigilant for opportunities to become outraged or offended, which really don't do much to solve anything, though it might make people feel good for doing so.
I don't think protesting against endemic rape will ever be a source of embarrassment.
