Psst. Hey. Guy who screenshot my Gamdavevris post. You said you didn't reblog my post because you didn't want to be rude to me on my own post so I'll extend you the same courtesy.
If you're going to rag on a ship, maybe don't do it in that ship's tag. Because if someone is scrolling through a ship's tag, it's probably because they like it and want to see more of it.
And what do you mean "Gamzee and Dave shouldn't be allowed around women"? I completely ignore Homestuck^2, so if they're misogynists in that, I don't care, but nothing in the comic itself points to that. Like yeah, Dave had a lot of toxic masculinity to grow out of and Gamzee is straight up a villain, but none of that had anything to do with misogyny? The most you could do is argue about Gam's association to Caliborn, but even then, that was more Gamzee being indoctrinated towards him than anything else.
In the character dynamics front, there are a staggering number of thematic overlaps, between Gamzee and Vriska in particular.
All three characters end up they way they do thanks to having abusive parents, with many of their biggest character flaws forming from the world views they create in their attempts to cope.
On the Gamzee and Vriska side of things, both characters trap physically disabled characters into abusive relationships with them in order to serve their own ends, with both relationships ending in the abuser killing the abusee.
Both Gamzee and Vriska end up idolizing evil people in their attempts to cope with their trauma (Lord English and Mindfang specifically), which directly motivates some of their most heinous actions.
Furthermore, the fact that both characters share motivations and have harmed people close to the other (Terezi and Tavros) makes their relationship deeply personal and it makes the similarities they might see in each other all the more damming.
Dave mostly avoids this pitfall by virtue of having better friends and a more stable environment. No offense to any of the trolls, but they could hardly be expected to keep Gamzee and Vriska's shit together when they can hardly keep a handle on their own. Especially when compared to the humans, who at least have more healthy idea of what their lives should look like next to trolls. It's what keeps Dave from falling into the pit of straight up villain, as he has a social safety net of friends who can look out for him and his concept of a healthy relationship isn't so fucked that he believes that, say, throwing Tavros off a cliff would be in any way good for him, or that he's willing to go to the same lengths that Gamzee is willing to just for some kind of affection.
Basically, Dave can see why Gamzee and Vriska wound up they way they did, because he experienced the same kind of issues they did, only they had no safety nets. When Bro died, Dave had Rose to talk to. When Tavros died, Gamzee didn't have anyone to talk to... or anyone who'd listen at any rate. As such, in this hypothetical OT3, Dave would be motivated by trying to get them the same help he got... while Gamzee and Vriska would try to drag him down to their level, as they see nothing wrong with their behavior.
