She’s kinda portrayed as a tumblr stereotype: Geeky, Otaku, incredibly insecure about her appearance, rather short.
Maybe, but I don’t think her resembling a stereotype is a bad thing, I found her very loveable. And how is that an example of the game being homophobic? I feel like you’re reading too much into it.
I don’t think Toby is homophobic anyway – there are two openly gay relationships in the game and even a character who could be perceived as trans (Mettaton). He definitely seems okay with LGBT folk.
Personally, as a gay man I’m willing to forgive a 16 year old for saying the f slur in the year of our lord 2009, especially since he hates everything about that game at this point in time.
