Oh god, yes. The whole idea of "cringe" and "cringiness" just seems juvenile (for lack of a better word). Feeling vicariously embarrassed about another person's good time and feeling the need to publicly distance yourself from them by calling them "cringeworthy" is the sort of thing a person does when they're a teenager, uncomfortable in their own skin, looking for social acceptance and worrying that people will think they're weird or gross or awkward.
I was like that when I was a teenager, but now that I'm actually out in the world and now that I see how little most people really care and how unimportant being accepted by one particular group of people really is, I've gotten a lot more relaxed. I might not understand what another person is doing, but why should I knock it? What makes the things I enjoy any more "valid" than the things they enjoy?
And I'm not trying to be patronizing or anything. I honestly feel like worrying so much about what other people do for fun is an immature mindset, and you'll enjoy life more once you grow out of it.
Sorry, I kind of went on a weird, overly long ramble there. But hopefully someone gets something out of this.
