It's only a matter of preference in this case, and different people find said pairings "cute". There's not much of an explanation as to why else they are "supported".

It happens between what occurs in the video-games and comics between the characters, the male protagonist, and Amy and Sally, the female protagonists (Sally = comics, Amy = games).

Come to think of it, it is kind of pointless and people should mostly just enjoy the games and comics while still agreeing on ideas with just discussion and no further argument, but everyone has a choice of what they support, debate about, etc.
