Vox Machina, and there is a new season.

Exactly. So if some being can change it's sex at will, is that cis or trans?

I agree with most of what you say, but human can absolutely change their sex. What do you think hrt does? Sex is a collection of biological realities, all of which lands you somewhere on the sex binomial spectrum. Some things are impossible to change (chromosomes and dna), while others are very much possible (ratio of hormones or sexual organs). I like this chart: 

don't these motherfuckers get tired of being mad about everything being woke. I can't imagine living my life so unhappy that I am angered by the single though of a trans person in media. These clowns need to get a fucking life.

On the contrary, they *love* being mad

As you said, it's impossible (at least for now) to change all of these biological realities. HRT is good for what it does, but it doesn't fully change one from one end of your spectrum to the other. Biologically, the only real purpose for a biological sex is procreation. Afaik, there's currently no way for someone who was born as a woman (left end of your spectrum) to procreate as a man (right end of the spectrum) or vice-versa. The rest is, to me, gender, not sex. (And yes, one could argue that e.g. infertile people or people after hysterectomy/orchiectomy don't have a biological gender, but then again, apart from procreation and maybe some medical stuff, the biological sex doesn't really matter and everything else is really just gender. And isn't that also the basis of the concept of being trans? That the biological sex isn't an imperative/doesn't really matter and that thus you can change your gender?)

Correlon is a god who uses avatars of both Sex and/or Gender. I don't see how that makes him trans in any way, because his avatars are not much more as if a player creates a character with a different Sex and/or Gender for his interaction in the gameworld. That doesn't makes the player trans. So how does it make Correlon trans? Have I missed anything in the lore? Please don't missunderstand me, I don't want to speak against trans or want to be seen as anti-trans in any way. I literally really don't understand this part and just ask for information or clarification.

If you're not cis you're trans, including genderfluids

I don't assume a mortal gender for any god, neither in real religions nor in fictional ones, I can't even see how a concept like gender (or sex) even would be possible at all with a formless/shapeless entity like a god. The entity would be beyond and above our puny mortal classifications and limitations of our bodys. It would be like asking what gender water has and then saying that water is trans or genderfluid because ice sculptures in male and female form exist. For me the sex and/or gender of an god is: god But maybe my main issue is that overanalize it, I often have that problem unfortunately. I hope that I have not said anything bad or hurt/angered anyone. If it happend then only because of my limited knowledge not out of ill intend. I used the male form because that's what is used in official texts in this case, so no assumption from my side. Thank you

Did they change their gender? Yes or no. It's a pretty simple system fam.

That is the issue and the source of my confusion. The god in question did not change the gender, it just created avatars. Those are sometimes created in a male form and sometimes in a female. But the god itself never changed gender (as far as I could find in the lore). Avatars are, as far as I know, entities that can be infused and controlled by the will of the god but it is not the god itself. Just like a human that controls a character in a video game, those characters are the avatars of the player but not the player himself.
