I don't think that's too wild an idea to have, considering there are plenty of times when the comic just straight up makes fun of shippers and fandom shipping culture as a whole. There are a lot of jokes made at the expense of people who enjoy shipping the characters together, and it just happens that some of these jokes were at the expense of those who enjoyed specific pairings. Yes, there are plenty of decent and good relationships and romantic arcs in Homestuck, but that does not really negate the point of my post, which is that the portrayal of a specific group of people isn't the best because they're stuck being commentary for fandom instead of just being in an actual relationship. There are a lot of good points made in OP's post, which is that we don't actually get to see or read any of the resolutions or conversations these guys had with each other that led to their problems and issues; we're instead just kind of told about it, and then see the aftermath later on after the fact. No one here is saying that them having problems in their relationships is a bad thing, but when you treat the two ships with men as just props to talk about yaoi and how "weird" it is and then treat any problems they have with one another really flippantly by just not elaborating further on why it didn't work out, or why they aren't together it can in fact kind of sting.
Especially since the comic doesn't do this for other relationships between the main cast. Like, we get an entire in-depth look at why John and Roxy's marriage fails, but the Epilogues flounders to really explain what happened at all between Dirk and Jake besides vague allusions to infidelity and illegitimate children. And even when the relationship isn't expanded upon as well, like with Roxy and Calliope, it isn't really treated as some kind of way to talk about real-life fandom. Now, this isn't to say that Homestuck is perfect at showing other relationships, it is just pointing out the stark difference in which these relationships were portrayed, and I don't think there's anything really wrong with pointing out that difference.
But anyway, I feel like we're kind of taking away from the original post and not really engaging with it by talking too much about whatever I said T_T
