A) most of her episodes are repetitive, Fluttershy is too shy to do something, then she learns that being a doormat isn't going to help, suddenly she's ASSERTIVE, lesson learned, group laughs, roll credits. Next episode: Fluttershy is shy again.
Devil's Advocate: that could easily be her characterization - in the show, she's only ever assertive with animals (the stare in general, wrestling a bear in LZ, calming down fucking Cerberus in IAT), or in unconventional circumstances (DS, PYHD), neither of those situations preclude her being an otherwise meek character
B) she's a lot like the irritating moeblobs that /a/ and weeaboos love so much, squeaking and hiding behind a rock was cute and funny the first time, not the thirtieth
C) A lot of her fans are disgusting weeaboos, and worse, people who think she's their pure WAIFU - waifufaggotry is pathetic already, without the subtext of "she's a submissive woman I can easily control!"
