Yeah, trans people today take so much crap from ignorant people it's ridiculous.
I think a lot of the negative stuff comes from the "movement" itself and people piggy-backing off of it for attention or other desires. Like you will see transwomen who make no effort to be feminine at all and demand (often threaten) that you call them a woman which almost takes away from the ones who did go through the transition. Given the name, I don't consider anyone trans if they are not in some way, shape, or form transitioning. It just doesn't make any sense. I think some of the younger people got trans and cross-dressing confused or they are simply doing it for attention which is why there is a real lack of commitment to changing anything. Then you have the push on children which to me is just wrong. Any level of sexuality or sexualizing of children's entertainment, school learning, etc. shouldn't be acceptable. Couple this with piss poor parents who almost force their children to be trans so they can be popular or gain attention... Makes my skin crawl. The whole "they/them" thing for people who seemingly have no gender while gender is just a made-up social construct, while it still somehow matters THAT much is too much for me. There are more than 2 genders and yet there are genderless people which is a gender identity itself because gender doesn't exist and was made up, and yadda yadda. I think that is an example of piggybacking that has hurt trans people because most people don't know how to deal with that kind of thing. I believe those people are just bored with life and going through a phase but again, it does nothing for trans people and if anything, it makes them look worse because they get lumped in with all the demands and weird internet genderized groups.
I will be honest, I never gave transwomen or transmen a second thought. I knew they were out there and I am sure I had interactions with them irl/offline but it was not something I had strong feelings about one way or another. It was just one of those "you do you" things... But when I started seeing people losing their jobs over misgendering, trans stuff being pushed onto kids, women sports being unleveled, and how everyone needed to start walking on eggshells for trans (and LGBT+ in general) people it pissed me off. It is the loud minority that ruins most things for everyone else though. I try not to throw everyone into categories and judge them all based on one person's actions but some people make it very hard for me not to slip into that mindset now and then so I can see how other people get to be so judgemental and hateful. It seems to be the way of the world right now, especially with social media. The mess that has become. We are almost being tricked into doing it and depending on "which side" you fall into, that determines if this kind of judgemental behavior is right or wrong. It is wrong to label all trans people as pedophiles because a few of them have been just as it is wrong to label all cops and racists because a few of them have been. Both of these ways of thinking are wrong. That is not how it is viewed though.
TLDR; Tumblr, attention seekers, social media mobs, and suck-ass parents made transpeople be viewed as something to avoid/dislike more today than just 15 years ago. We are going in reverse, sadly.
My mother was sort of the inverse of that, I suppose, almost looking to bully a trans identity into me...or well, obviously more just hating on the fact that she had a male child, and that caused me to build up a level of dysphoria that's stuck with me.
As for the whole women raising boys to hate themselves... That has been an issue for a long, long time but it was mostly within black families. I had a few black friends growing up and the mothers, grandmothers, and aunties would all treat the boys (brothers of my friends) worse than them. Often as if they are resenting them because of the men in their life who hurt them. You see it as a common trope in programing and movies as well. It is sadly a common thing which I think contributes to boys growing up to be in gangs, treating women like crap, and getting into trouble. It's not my place to remedy those issues though and I would probably get called a racist just for pointing them out. Outside of that, you will find a growing issue of children being raised by mothers and taught by schools that any level of masculinity is wrong and "being a boy" is terrible. I grew up as a tomboy. Had my mother started beating me over the head that I should be more feminine, I would have either pushed harder to be like a boy or just hated myself as a girl. I don't think parents understand how powerful their words are with their children and how they can manifest a wave of self-hatred that lasts a lifetime nor teachers for that matter. This could be a contributing factor in why there are more and more trans people today. We tend to learn and better understand things years after the fact so I guess time will tell.
This is one of the reasons why I think it is very important for anyone considering transitioning to speak with someone first and really hash things out before deciding on something like this. Once you start the hormones and get the surgery, there is no turning back and it can be very, very expensive and very hard emotionally. Sometimes the feeling of self-hatred is not a "YOU" problem but rather an issue with someone else's words or actions toward you. And shame on them.
