You can't generalize.
You can. It's very dangerous for the majority to do otherwise.

In the matter of reforming things, as distinct from deforming them, there is one plain and simple principle; a principle which will probably be called a paradox. There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, "I don't see the use of this; let us clear it away." To which the more intelligent type of reformer will do well to answer: "If you don't see the use of it, I certainly won't let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it.
If Ava, or anyone else, thinks that sex segregated spaces shouldn't exist then they need to explain the rationale behind them in the first place. In this instance it is for the privacy, dignity and safety of women and girls.
They then need to explain and evidence how the risk from males no longer exists and why women and girls no longer have a right to privacy and dignity.
