I’m a member of the other population subjected to involuntary electrocution of the brain, being defined as “sick”, subjected to determined efforts to “cure” us with or without our consent, described as a menace to decent citizens, etc.
I can certainly relate to the fury, as well as being tired of having to rehash the same basic “we’re people and we really should be accorded the same rights as other people” fundamentals over and over and over and over again.
I do think Jimmy Chitwood is fundamentally right, though. I learned a long time ago that being patient and being courteous, making your point and yet listening, even to stuff that infuriates you, finding strands within it that you can acknowledge as reasonable and separating them from the specifically offensive parts and explaining why they are offensive, rather than branding the other person(s) as a hatefully discriminatory categorical oppressor committing social injustices by even voicing such thoughts.
It’s not just the person you’re squaring off with — it’s the audience. You may never reach the one who insists that there’s something wrong with you or, worse, that you deserve certain (mis)treatments, but if, to the others tuning in and watching from the sidelines, you’re the one keeping your cool and considering various perspectives while the other person is frothing at the mouth and hurling condemnations and defending aggressive, violent, or invasive responses to your existence, you may reach many of them.
The cultural left, at some point, appears to have adopted an attitude of “we aren’t going there again and discussing that subject yet again, it’s oppressive to force us to make the same basic points over and over again; if you haven’t been living under a rock in a cave at the bottom of the ocean you know you’re wrong and you know why you’re wrong and you know it’s already been established that you’re wrong”. Unfortunately, they’re wrong 
As long as the folks we’re coming into contact with are not the very same individuals with whom we’ve already had these reiterative regurgitative discussions over and over again, yeah we do have to go there again, because they haven’t been exposed to our perspectives yet, and because “you’re not merely wrong, you’re an evil person for not already knowing how wrong you are” just isn’t a very compelling argument. Even for something we really thought we’d succeeded in making mainstream cultural canonical truth, like what racism is and why it is evil and wrong, it’s sometimes necessary to start over and explain it all once again.
