People are allowed to set boundaries on their personal lives.
Those boundaries may reflect them being racist, sexist, or whatever but they are still allowed to have their boundaries. A white person who won't talk to black people cannot be forced to do so, though we can try to persuade them.
However, it can also reflect their life experience. In this case, I think the restrictive bios reflect the latter: women who have been harassed or had guys not take "no" for an answer setting a boundary to avoid that situation. That's not sexism, that's dealing with a problem in their life in a reasonable, rational way.
All of this is saying that we cannot always judge a person by the boundaries that they set. Sometimes there a good reason for the boundaries, sometimes there is a bad one and unless they are public about their reasons, we cannot necessarily make assumptions about who they are or what they believe based on those boundaries
