I'm divorcing Hussie's decision to make Dirk and by extension Bro gay from earlier Homestuck because I don't think Hussie outright considered the implications when making that choice. We have seen multiple times in the comic how Hussie will make a decision for the story and then not consider the wider implication: re "feeling caucasian".

I'm also trying to be charitable to the fact that yes, you can depict a gay man being abusive like that, but Dirk's arc fixates on his sexuality in such a specific way that then if he DOESN'T undo the negative stereotypes tacked on by Bro's depiction, it leaves a homophobic etching on the wall. Making Dirk gay was an intentional character choice by Hussie, and making his sexuality a KEY POINT OF HIS STORY was also an intentional decision, thus you cannot wash your hands of the negative implications stretching forward OR backwards, but I think everybody can at least be more charitable to what was already written as at the time of authoring, Bro wasn't a gay man or at least we had no reason to outright believe so.

And yes! You're literally adding to my point: the first piece of information we get regarding Dirk, whose arc is going to surround his sexuality and how that impacts his friendships, is that he now has a robot that will try to molest his romantic interest. Does that not trouble you in the slightest???? The only reason this story content mildly scrapes by is because Dirk winds up existing in antithesis to these negative gay stereotypes for the briefest moment come the end of Homestuck.

As for Davekat being walked back, I literally cited TWO moments where characters who were with them the entire journey explicitly state they're dating. Vriska and Terezi first, and Jasprose, who may I remind people has a degree of omniscience at this stage, says Karkat is in a relationship too.

I think you're coming into a thread about how Homestuck treats it's Gay Man and how Homestuck treats male queerness and reducing it to just being about Dirk. Again, this comic opened up with Dave and John being homophobic to each other on a regular basis, that alone pinpoints that the author had some things to unpack. Karkat makes use of a homophobic slurs in act 5!

How you can acknowledge all of that and say "yeah, the author doesn't hold any latent homophobic views" will go beyond me.
