I’m not saying people should do it. I’m just talking about a fundamental principle to keep yourself happy: to not be hurt by what other people are doing. In the end, you can’t control what other people will do. But you can control your reaction to what they do.
Of course, everyone is also allowed to disagree with this advice. I’m just sharing what works for me. If someone wants to feel bad/offended about someone making a fake nude of them, I don’t want to stop anyone doing that (and I can’t).
