I've been having issues with both the show and its fandom, from how it tackles and rends some stereotypes while unconsciously glorifying others (women can be any shape they wish, but they should still be pretty), to how the fandom has actually attacked the show's creators for similar issues (such as the poor case of Lauren Zuke).
I've heard once that, in terms of social justice, it's like some of the first space launches: not perfect at all, but still a step in the right direction. I believe that to a point. Much of the rest of the time, I'm more annoyed with how it favors metaphors of social justice issues over developing coherent storylines. Some episodes talk about how love is not something to throw around, while other episodes almost glorify "puppy love" to the point of almost encouraging codependency above internal emotional development.
Truthfully, the mixed messages of the show apparently come from characters with mixed feelings, but I feel the show doesn't make this obvious, as if we should take everything said on the show with a grain of salt EXCEPT for the major characters.
