Also, sorry for a third response but I'm firing off as these thoughts form. I do think Dirk being read as a gay trans man is a valuable perspective, but I do not believe Hussie ever made that an intentional part of his character when he first wrote him.

Dirk's focus on his sexual identity is a big part of his character and I would like to believe that if Hussie was truly going to write a trans character from the jump, that part of his identity would also be given equal focus with regards to how he fits into the story.

That being said, I still don't believe it negates much of what was said. Whether or not Dirk is trans, I still think this is a bigoted depiction of a gay man. Trans people also get the groomer/sexually abusive towards their children and other queer people cudgel tossed their way.

We can have discussions all day about misogyny and examining how it unfolds in Homestuck, but we can also do that without bastardizing what was otherwise a rather decent depiction of a gay man. Dirk didn't need to exact sexual violence on his family and his ex boyfriend; that was just done to add more "drama" and showcase how EEEEEVIL he is as an author.
