Just let people enjoy things, even if it's "cringe", even if they "don't understand it", even if they can't explain why they like it, even if it's just a phase. If you just want to enjoy things without being judged or shamed about it, then let others enjoy theirs, even if it pisses you off, it doesn't mean you get to judge someone's interests. Think before you embarrass someone over their taste in anything. If you feel that being judged by your interests is unfair, don't do it to others, that just opens you up to receive the same judgement back. Ask yourself why are you being so judgmental before you say something, because this type of behavior will tell someone else what kind of person you are: someone they don't want to interact with for being cruel, who is ignorant, who is judgemental.
Cringe culture is really about passing judgment on things you don't even know, on the simple fact that you can't see people enjoying whatever they enjoy.
