I saw someone here saying that men should admit to being MGTOW in real life, and heard of a teen here that said he went around at school saying he was MGTOW. There's really no need to admit to anyone that you are MGTOW. It just paints you as a target for feminists, and people in HR to want to fire you for misogyny. It should be obvious, but maybe it is not. A quick search about MGTOW on Google links to articles and definitions that says MGTOW is a misogynistic group of women-haters. It's not very good for your career or school in the long run, when people look it up and see that. Just tell people you are a bachelor and not married. No need to get into the details. If people ask further, tell them that it's none of their business and you would rather not go into that.

Also, this reminded me of this video below. It is a good analogy. Don't be the gay plumber using "MGTOW" instead of the word "gay".
