I see where you're coming from with the whole "transitioning kids" things, it really bugs me too. I do still think that, in America at least, I have no right to get in between a trans person and them getting the care that they need, provided they are a consenting adult, despite this I actually agree with a lot of this here, these are valid points to raise, I do not however think this applies to all or even most trans people, they are a VAST minority of the population and I think you can find just as many instances if not more of cis people doing just about all the behaviors you mention here besides transitioning itself.
There ARE however, a LOT of people that don't share your concern, or just pretend to, because they just hate trans people. You're obviously not one of them, but there ARE people out there who have an irrational hate of trans people. They DO exist.
People don't hate transgender people -- that is, people who suffer
genuine gender dysphoria and have tried surgeries and treatments to try to better their quality of life. I have genuine empathy for those people who suffer from such a condition.
However, those people are literally so small a number on the global scale that you could visit every country on Earth for a week, do touristy things, and
never encounter them once on the streets or anywhere else.
What concerns people with common sense and a brain, and what focuses a lot of disgust and hatred from these people for "transgenders", is that the masses who claim they're "transgender" these days,
especially in the last decade, are actually "trans-trenders" -- many of which go on to groom other victims, commit outright heinous acts because they're sick (such as sexual predators against women and children), or because they're ill (such as untreated mental illness), or because they can use it for an advantage (such as trans-trender women getting gold in women's sports because they're just men in fucking dresses!).
At best these people are victims themselves (groomed, as in actual children, preteens/teens, vulnerable people, et cetera) or just ignorant (such as dumb teenagers thinking it's another subculture, like being a Goth, Emo, et cetera); at worst it's an excuse for predators (such as teachers) to be utter degenerates and to fulfill their sick lusts and desires, or for people to gain a benefit by claiming to be the other gender (such as the aforementioned sports example).
Vulnerable people are being preyed upon. Vulnerable or ignorant people are mutilating themselves and destroying their lives without knowing/realizing the consequences. Trans-trenders are literally up-ending society because of their delusions, and worst still their delusions and the lies they've been sold on are being supported by malicious actors who benefit from this (such as the medical industry, policalization, et cetera).
So, yes -- the hate is justified 99% of the time.
Also, don't call people "CIS" -- an outlying minority trying to relabel the majority is
incredibly fucking disrespectful to the majority of people in the world.
I'm not "CIS". I'm a normal man. If I were gay or Bi, I'd be a gay or Bi normal man, not a "CIS straight, gay, or Bi man".
