This seems like a you problem. I have quite a few repos made before using "main" was the default in GitHub or Git. I have not changed them, and I have never spent more than 5 seconds thinking about it, let alone worrying about being considered "less of a person" because of it.
In the spirit of genuine curiosity, who is making you feel like less of a person wrt the choice of main/master, and how are they doing that?
It sounds like you're saying that git maintainers are intending for you to feel like less of a person because you don't agree with their choice, but I don't understand how you arrived at that conclusion.
And git isn't preventing you from having a master branch. In fact, they're providing instructions for people who prefer that.
