What bothers me about this fictionkin/stan culture is that it makes people feel the need to defend the honor of/protect fictional characters, which leads to artists being less willing to try shit with different character dynamics and themes. I remember in SVTFOE fandoms, anything interesting about MoonToffee and Toffee as a character went out the window because "wahhh MoonToffee is inherently abusive". The one of the main MoonToffee artists deleted all her shit because of it.
I'm not saying heterosexual Adora is even an interesting or good concept, but it can be. However, if artists/writers can't try that shit out, then we'll never quite know.
