As seen on http://nimaru.deviantart.com/art/The-Brony-Info... (click the link to see the full sized image since you can’t read it at the zoom level Redbubble gives you).
DO NOT BUY SMALL VERSIONS! There’s a lot of text on here and if you don’t get one that’s at least 24 inches long (30+ highly recommended!), no one will be able to read it.
I spent weeks designing this infographic summary of the major reasons people give for why bronies are “weird”, “wrong”, or “sick” and why each point is ridiculous.
Bronies are just like fans of anything else in pretty much every way and this infographic is designed to make that point as clear as possible.
If you buy a poster and put it on your wall, you’ll have a ready-made answer to anyone who gives you crap at home, work, or school. It will show them that fans of anything; sports, hunting, music, movies, etc. are really all the same other than the thing they’re a fan of.
