My perspective is that both with regards to how I feel and with regards to my friends perspectives, the moment that Hussie decided to make one of the main drama pieces surrounding Dirk and Dave be their sexualities, they had a duty of care for how they were going to portray them going forward.

At the time when Homestuck was current content, Hussie was assumed as a cis straight guy and described themselves as such, so it was a very surprising turn to have such a thorough depiction of a gay man experiencing internalised hatred but not due to abject disgust.

I can specifically remember growing up and having a moment where a person my age told me that they liked me, but due to my orientation I had to turn them down and they told me that ruined their birthday. It's kind of something I carried with me a lot, its fucked up and I know that I'm not to blame, but it does blindside me that Homestuck captured that feeling with Dirk, the immature internalization.

So, considering especially Dirk has so much of his identity tied up with his sexuality and how that's one more reason for him to loathe himself, I find it a bit homophobic that his role in the Epilogues becomes one of a sexual predator and a coercive force to his family. It's an epithet that gets tacked on to gay men a lot.

It's also why when people discuss Dirk grooming Rose, I have to roll my eyes into the back of my skull. I don't fault people for drawing that conclusion because the story definitely gave supporting arguments, but I don't think its any degree of sound writing to portray a gay man grooming a lesbian, or allude to that dynamic.

And especially after Dirk experiences multiple moments of heterosexuality flaunted in his face to fuel that depression.

As for Jake, his tendency to sleep around feels like it just parodies the promiscuous bisexual trope.

I would be curious to read how sapphic people feel with regards to portrayals of their romantic spectrum. I don't particularly feel that Homestuck does well on that front either, but notably because Homestuck just glosses over it as something to be significant; I'm not aware of a particular moment where a character like Rose or Kanaya have their sexuality become an integral plot point or they have heterosexuality weaponized against them.

Much can be said about Vriska and Terezi too, for example I think Vriska sleeping with Gamzee is just INSANELY and disrespectfully bad writing.
