I don't hate gender non-conformity, and I have sympathy for gay people who are incorrectly convinced that transitioning is a good choice for them due to lacking support as children. Like I said, I think that the modern trans movement actually preys on effeminate gay boys and butch gay girls and convinces them to mutilate themselves as a justification for the ludicrous belief in gender identity. I am firmly convinced that "trans" children, if given support to explore non-gender conforming interests without declaring them "a girl inside", will not transition, and that the homosexual transsexualism would almost entirely disappear. I think, similarly, that addressing the insecurity young girls feel in their sexuality and relationship to boys would eliminate practically all FTM trans people. All the would be left would be the coomers.
That said, your comparison to fandom is sort of telling. In the same way furries defend the worst of their ranks with their sense of community, the same is true for trans people. Right now, fetishists like Yaniv can literally prey on little girls more or less unimpeded because the trans movement provides support and cover for these predators. I'm not about to go out on a trans killing spree, but I absolutely do hate the movement for the people it harbors and the behaviors it enables. If "real" trans people don't want to be associated with these degenerates, maybe don't defend their identities as legitimate. As it is, you go to the discussion of any trans offender anywhere on the internet, and there's guaranteed to be at least one person there super concerned about whether or not you're misgendering the rapist/serial killer.
Re: Andrea Long Chu. I like how nowhere in the article does it explain why the suicidal person/razor blade example is incorrect. It literally just says "yes, you would be violating the Hypocratic oath, but I want it, and being trans means that I get what I want". He seems to think that by just acknowledging the argument, he's countered it, but it just makes the choice to help on the doctor's part more crazy. The one logic I could accept for transitioning is that it counts as harm reduction when nothing else will work, but as Andrea showed, that argument leaves open the door to it not being the best solution in all cases. It leaves open the possibility that it is a mental illness, and that choosing to transition can cause regret. And facing that reality breaks the whole illusion apart. It's better to pretend that they can never be happy, then face the possibility that they are just a sad pervert.
