Voice chat for raids or teaching people primals or callouts is fine. The few times I've played games that had voice chat people would end up wanting it for even the smallest things and kick you if you didn't. Then yes there's the whole being female and being treated like a normal person sans voice chat and seeing that fly out of the window the instant your voice is heard. It tends to go one of a few ways. One is their mind is blown that a girl is a gamer and they end up repeating themselves. Another is they go the hur hur go make me some food route where it's clear that now they're just going to be a sexist jerk. Or they start to non stop hitting on you. It's rare to get the oh wow it's a girl and then play on normal like nothing happened. Yes there is the ignore function but people shouldn't have to do that in the first place just due to gender or whatever.
