The Stonewall Inn was a gay bar so we know that Zazu Nova must have been there due to being a gay man. As the previous iteration of the website describes Nova as "queen", "she" and "transgender woman", this means that in 1960s terminology Nova would almost certainly have been understood to be a transvestite, possibly a drag queen.
Sources on the web refer to Nova having involvement with the Street Transvestites Action Revolutionaries group, which fits with that description also.
I don't think anyone is arguing that you should be barred from taking your hypothetical two-year-old daughter into the men's bathroom if the need arises. That's really not the issue.
Interesting to see the difference and I agree that's an inaccurate edit. For historical accuracy it should describe Zazu Nova as a gay man who was also a transvestite or drag queen.
Doesn't this change make it more historically accurate? In 1969, the year of the Stonewall uprising, the "TQ+" hadn't been invented yet as a cultural concept. The Stonewall Inn was a gay bar and was being targeted for that reason.
Being told that you have to follow the same rules as everyone else for e.g. spaces designated to be used solely by the opposite sex, doesn't seem so bad.
