From the River to the Sea

Instead of a cutesie reference to film censorship it was an explicit statement of defiance of Maryland's criminalization gay sex, which was not repealed until 2002. This wasn't a guy saying "Oh they can't put what I do in the movies according to a completely voluntary industry code" he was saying "The State of Maryland wants to put me in jail for being gay and having gay sex."

Episode 5:

During the bar scene Jax laughs and makes a comment about Zooble being a tattoo artist and a bartender, two queer stereotyped jobs. Thing is, this is pretty insider knowledge since these stereotypes are not as widely known in mainstream cis-het spaces.

When Jax called his tail as the 'pinnacle of masculinity', he finds out it's missing.

And more importantly, there's the Jax maid scene.

First he acted infurated, but as he shifted attention to other stuff, he acted quite comfortable in it.

There's the fact that while Evil Ragatha told Ragatha nobody loved her, Evil Jax told Jax he looked good in the maid outfit, being a possible reflection of his internal and repressed thoughts.

Episode 6:

Jax, when pushed by Pomni, says "you think I'm a misunderstood chicken fetus in an egg that is waiting to be cracked open!", and for those who don't know, egg is trans slang for someone who is trans but is not conscious about it, and cracking open is realizing it.

Episode 7:

Jax is the only who didn't want to wear a swimsuit and expose his body, something common in people with dysphoria

He also talked about Zooble's ability to change their own body with a grain of envy.

One of the most explicit details is Jax's room, which looks like that of a small girl, and since apparently the characters can't design their rooms, it could be based on Jax's mind.

Episode 9:

We need to start commenting under other people's posts about how to properly warn for flashing lights and eyestrain. We need to be emailing and calling companies about their possibly triggering advertisements that could induce seizures. We need to stop tolerating ableism and start speaking up for the more vulnerable.

Also, stop putting epilepsy warnings. That's like saying "warning: schizophrenia" on a post including unreality or "warning: dyslexia" on a post with a typing quirk. First off, the disability mentioned isn't the only group of people that this could trigger. Second, it doesn't truly get the message across and instead makes it worse for those with the disability-- scrolling through the epilepsy tag on Tumblr should get you to view the content of other epileptic people, but no, you just get a bunch of flashing lights and eyestrain, even though you could instead tag for, oh I dunno, flashing lights and eyestrain.
