whereas the shippers are doing it for wank fodder.
Maybe that's
your reason
But anyway, in somewhat more seriousness...
This is a comic where romantic relationships exist, and where - yes - people sometimes have sex, sometimes all but on-panel (Sven and Gina Riversmith, for example). Yet there is somehow something wrong with what is basically nothing more than talking about potential future plot developments (of various degrees of unlikeliness) - without even making it about sex at all beyond the inevitable fact that the comic isn't shy about acknowledging that people who are in relationships sometimes (but not always) do eventually have sex. And who said anything about it having anything to do with being a same-sex relationship? Though, if that is the reason that Faye/Angus "shippers" are spared the bulk of this scorn (they do get some hate, but it's more about the supposed "fact" that Angus is a stalker than it is that it's "creepy" to think about two characters being together), then... well, that says more about the people calling it creepy, now, doesn't it?
