And how do we discern if the environment is hostile, for example, if there is disagreement amongst men in a women's psych class? Do we decide based on whichever side is larger? Whichever side is louder?

And what if the perceived hostile environment is, in fact, not hostile? What if it is the result of being exposed to new ideas, new group dynamics, an inability to separate oneself from the group they are a member of, breakdown in communication/terminology, etc.?

What if actions taken to improve the environment for one group is felt to be hostile to a different group? Then what?

No, I think this problem is significantly harder than you believe.
