It’s a step back if you are talking about sex and not gender expression. Not everyone is from the US or a Western country. The broader question is would it be allowed even with that. If it was done for safety reasons, you can make an argument that it’s discriminatory towards men because you are assuming they will be violent. Pretty sure the same justification was used against black/poor/immigrants/etc. If it’s not for safety reasons, and just a thing, could you enforce it? You can create a place called “A Woman’s Space” but would men be legally allowed to go?
