I don't use that argument cause I am confident in my masculinity. I'll even admit that its shameful and lame to be brony, but whatever. It doesn't cost me enough man points to make me not a badass.
Two of the most badass people in the world could possibly be bronies. There's John Cena who is an admitted anime fan who played on some of Rarity's dialogue in a promo and CM Punk who utilizes Twilight Sparkle's symbol on his trunks and shirts.

How many man points does it cost to be a brony? And do you get a discount if you decide your favorite pony is Big Mac?

That's a good question. Lets say your average man has 100 man points. I'd say being a brony would cost you about 105, however, liking a badass pony like Applejack or Big Mac would give you a 20 point discount, but having Rarity as your favorite pony costs you an extra 20 points. This is just loose speculation of course. And I have more man points than the average man because I'm a former bouncer.

O wait, not an actual quote from the video. Damn you, misleading description!

The funny thing is, this was from before I started watching the show. It's weird to see year-ago me troll-commenting on MLP.

I'm not a brony, though, and I don't know why you think I am. I think the show is brilliant, yes, but I don't consider the show to be a part of my personal identity, and I don't associate with fans outside of the other PoEnies here on poeTV.
