Give it a rest. She's probably had a really bad day, and what's she's saying isn't false. Great, yeah, she probably shouldn't have said that, but she isn't wrong. Heck, my sister came across pony pr0n on safesearch, so yeah, the sexualisation thing is pretty bad, and tbh Bronies should put up with the hate.
Cue "Not all Bronies are all like that".
Either way she was kinda unjustified, but she made a good point.
