The issue in a nutshell.
There are people who would prefer you state that although reality is X, they would prefer the pretense of everyone that it is in fact Y.
People have supported this through niceness, kindness and lots of awareness of difficult feelings and struggles for which they wish to be supportive.
The question is now, how far people should continue to support this when those requesting this enablement have begun to totally take the piss and to insist that Y is literally true, and that X no longer exists. And this has a major impact on many of those whose equality and access depends on X.
At that point, we're into issues of coercive control an abusive behaviour, and whether there are some who it was not kind to enable to believe that Y was real in the first place. Because there's no getting away from X.
