I understand. I'm the same way with this fandom. And I know you don't wanna hear it but I'm the same way with shipping in the cartoon fandom too, believe it or not! I don't ship any in there and I just completely ignore all those fans of couplings in that crazy fandom. They try and reach for anything possible (like Gar and Raven for example)and I just don't do that. Now the comics is different for me, and I personally liked how Geoff wrote it out. I can actually see nice polite shy Raven with Gar, but not when she's incredibly mean and snarky, like how it is in Titans. So I can see where you don't like it and find it incredibly annoying.
And reading that Marv quote just reminds me of how he just doesn't care anymore. I guess he's just not as invested in his characters as he was back in the good old days. :\
