It would be convenient if it's cultural because it would explain why transfeminine nerds retain "masculine" nerdy interests while avoiding a faux pas.
If I "retained" masculine interests, it's because I still enjoyed them, even after I no longer felt pressure to act like a man.
I played Harvest Moon, Animal Crossing, and preferred beautiful/cute games before I realized I was trans. I probably would have played more if I didn't care about my friends calling me a f--. I also like plenty of "guy" things but so do plenty of cis women. I had this exciting period of trying all sorts of new things when I came out and I'm only just starting to see what I truly enjoy when I don't worry about the opinions of others.
