Did you know that a lot of ex-jahovas witnesses will go over the top to celebrate holidays? Most of them will even have one holiday they will pick as a favorite, and just go ALL OUT on that holiday. Holidays are considered a sin in JW society, and celebrating one is a good way to get shunned.

The same applies to trans people. If you've spent your whole life identifying with a certain thing, but been denied that thing because of some arbitrary reason, you'll almost reflexively 'overindulge' when you're able to finally just enjoy what you like.

It's a bit of a chicken and egg situation. If society just never cared, and let boys enjoy 'girly' things and vice versa, the situation would almost certainly be completely different. For one, they may never develop any kind of dysmorphia to begin with, but even if they do, they haven't been denied the things they want, so there's not the overcorrecting we sometimes see now.

I love that gendered toy sections in stores are totally gone. There are just categories now. There's still usually a Barbie aisle because there's a million barbies and an action figure aisle because there's ten times as many action figures, but they're not separated into girl's toys and boy's toys like they were when I was a kid in the 80s. There was a boy in my elementary school who had a Cabbage Patch Kid and got made fun of for playing with a girls' toy. I hope getting rid of those barriers in stores has helped that sort of thing. My daughter didn't really seem to get the concept of 'this was a toy boys played with' and 'this was a toy girls played with' until she started enjoying going to antique malls.

I think if someone defines certain items or activities as celebrating their gender, whatever those items or activities are, I think it’s fine! I don’t think Trans folk are doing any harm by gendering things, it’s an expression of them and their gender identity.

We don’t need to tells boys not to have tea parties because it’s girly, but if a boy or girl decides that their tea party is boyish or girly, then good for them.

yet they also are often some of the biggest perpetrators of gendered identities.

You're reading too much into it. Society says that tea parties are feminine. Whether that's inherent to gender, or entirely a social imposition doesn't really matter. Trans people are NOT saying that if you like tea parties then you're a girl. But if you like tea parties, wished you could wear dresses, wanted sleepovers with the other girls instead of the boys, then that doesn't necessarily mean you're trans, but it might be something to consider.

Think about it this way. Trans people were denied the opportunity to participate in these stereotypically feminine things without feeling weird. And I don't mean weird because people tell you it's wrong to like that stuff. That's definitely part of it. But it also just feels like you're an alien. You may be participating in tea parties, and wearing dresses, etc. But even if that was totally normal, it would still feel wrong to be doing that as a boy.

I don't know if any of that made sense. But I think you see trans people wanting to be able to experience stereotypical femininity and misinterpret that as a desire to impose those stereotypes on others

I always found it interesting that society is in general headed for sex-(and IMHO also gender-)correlated roles ceasing to exist,

~~In certain society most sex-correlated roles were sent to GULAG~~
