The good parts:
They do point out the original Big Hollywood article was needlessly insulting and over generalized.
Bill Whittle has excellent points on the increasing trend of escapism and Peter-Pan syndrome. And that My Little Pony is no different from Starwars obsession and mentions his own past Star Trek cosplay. Kinda wish Bill put up a photo of him wearing Spok ears.
Referencing Obama's base via rainbow-farting-unicorns.
The bad parts:
No footage at all from the show itself. That shows a pretty thin setup on exactly why someone might actually like it. And betrays a deep ignorance of the show itself (like how the main characters are actually adults with careers and responsibilities and the like).
Misuse of the term "Brony" which means any adult fan instead being used to talk about people dangerously obsessed with the show.
A lack of realization that the series creator Lauren Faust intended the show to have broad appeal.
All together it comes off like saying all Star Trek fans are basement dwelling loners. Or all anime fans are emotionally stunted perverts. Or that D&D players are all garage-living Satan worshipers.
I got a real Mazes and Monsters vibe of people who have no idea what they're talking about recoiling at folks having fun with something they find really strange.
Which is a shame as Whittle has a really good point.
One problem I see with us Bronies is being too aggressive getting people to watch and defensive with critics. The latter is self-explanatory, but the former is interesting. Very few Bronies started out as fans of My Little Pony, and most can't stand to watch the previous generations of the show. They are much worse with insipid characters and hideous animation.
So for the vast majority of the fans there was a conversion from hating MLP and not wanting to watch, to being apprehensive to watching, to watching, to being a fan. Thus many Bronies see any non-fan as a potential fan.
Which is not true, and can be a bit annoying to non-Bronies.
