One of the comments there actually makes a decent point if you change 1 word.

When you start to live as a guy, you become more removed from the uncomfortable and degendering degrading experience of receiving sexual attention from straight men. Then you slowly learn to stop suppressing the part of you that desires intimacy with men because your interactions with men are no longer tinted by that dysphoric anxiety. Your fear goes away because you can now be confident that men who are interested in you aren't expecting you to be something you're not.

Person seems oblivious because wtf even is "degendering" but they might be feeling the specific effects of existing as the female gender in a society with men who objectify women as sexual objects.

They are also probably acting like the TRA version of political lesbians. They only care about the trendy identity of being seen as gay and somehow manage to reject their entire sexuality in order to be seen as gay but sexuality is a strong instinct. They can't resist that urge so they pretend to be a man in order to maintain the gay identity and also avoid the perception that all straight men are awful. The fact that they feel more comfortable with gay men is just based on their own stereotype of what they think gay men are.
