So there's this person I've been following on yt for awhile now and every video I watch I try to figure out their pronouns because I want to comment but I don't want to disrespect them

This is the person and I blured their name so people don't hate them I don't want to get in trouble with anyone and here is a couple of their cosplays

They're really good and I enjoy watching their videos it just drives me nuts trying to figure this stuff outqnd if you comment why don't you ask?
I don't want to come off as a creep!
