A lot don't, but it's nowhere near 99%. The /r/ActualLesbians subreddit has been taken over by TRAs. If you say that lesbians are exclusively attracted to females or that lesbians don't like penises, you get banned for transphobia.

Lesbians had to make a new subreddit called /r/TrueLesbians just so they could freely say they arent interested in males or penises.
There are a lot of stories on /r/GenderCritical from lesbians who were ostracized from their LGBT club or social circles for rejecting trans women. It's a thing.
