The point is not that they are not entitled to their chosen identity, but that they should be more sensitive to issues that go beyond the identity and not try to suddenly magically become part of it. Nobody will forbid a white man to use ghetto clothes, but if he suddenly starts to act like he is suffering with racism, that will sound weird. If trans people can’t understand and empathize with the fact that they did not experience the prejudice before, and have the common sense to stay out of the specific issue, then sorry but they are the ones being insensitive and screwing their own chosen ”equals”.
