Also unpopular opinion: I don't think you'll find many objective reasons. There are many parallels between trans people and gay people and there are no good reasons to hate either. Most of the hate against them boils down to "it's icky and I don't understand it. Also something about religion." If you're lucky, you'll get an appeal to nature fallacy. The regret rate of chemotherapy is higher than transition and the satisfaction rate of HRT is one of the highest satisfaction rates of any treatment. Suicide rates plummet after transition and ever more so with supportive friends and family. If the argument is that HRT is enabling delusion, then what is the alternative? Therapy, much like conversion therapy for gays, has been thoroughly debunked and has an entirely ineffective success rate. Furthermore, therapy is legally mandated to get hormones. To get surgery, they need over 12 months of monitored, professional therapy. They literally do go to therapy and the professionals agree that HRT is the best course of action. For better or worse, transition is the only viable treatment, and it seems to be for better. Studies have also shown that trans people are not if fact crazy. The areas of grey and white matter in the trans brain have shown to consistently be more similar to their identified gender and this is with and without the influence of HRT. Honestly, being trans seems at worst to be a birth defect in terms of a mismatched brain which would almost make them intersex i.e. non-typical genitals. We don't hate people who are born with their junk a little odd and need fixing. Claims of trans people being pedos that creep in bathrooms are wholly unfounded. This simply doesn't happen in reality, and more to the point, if someone wants to go in the other bathroom and creep on someone or rape them, they are just going to do that. We don't have guards at the doors making sure only the right people go in.  If the argument is they are mentally ill, well yeah, but so what? Gender dysphoria is in the DSM and so is depression and OCD and everything else. Are we supposed to hate all mentally ill people? We take measures when people cause harm to other people and trans people do not. Everything else I've heard against them seems to be isolated incidents from bad apples that occur in any group of people, and Tumblr. There are no actual studies demonstrating consistent antisocial behaviour linked to being trans. There are batshit crazy gays and LOLcows everywhere and the "I identify as a 6 year old" morons are cherry-picked and not even related to being transgender. I think trans people are poorly represented because the fat Tumblr attention whores claiming to be a million genders with bright pink hair just for the sake of clicks shout the loudest. I agree that more than 2 genders do not exist in biology and what you find is that actual transgender people do fit within the binary and they tend to transition and go about normal lives. The most confusing part, in my opinion, is how angry people are considering the population. We are talking about less than 1% of people. Even if you disregard all of this and still hate them because you think they are making stupid choices, then what about people who are into extreme sports? Is that not "stupid," "unnatural," and a cause of "unnecessary" medical spending? It seems to me that, at worst, you could call trans people a niche group you disagree with, not this threat to modern society it seems to be labelled as. For that matter, look at the shit people do when they are drunk for an example of stupid choices and abuse of a legal substance and that's a lot more than 1% of people. I'm willing to admit that Voat has changed my opinion on a few topics, but not trans people or gay people. You can't just call them faggots over and over again without any scientific argument to reinforce a justified hate. No one says you have to like them and no one says it's not a little weird, but these people could always, you know, not care? I've done some reading myself and I really don't think you're going to find a reason why they are so horrible and wrong. We came around on gays because there was no actual reason to hate them and I believe the same thing will happen with trans.
