Okay okay I'll stop leaning too hard on the bronies after this one, I swear.
For a community built around friendship, I've found most of my interactions with brones has been on the unfriendly side.
In my experience it's been more like the other way around. Which makes it way more hilarious, really.
Heck, I'm on a pony forum founded and populated by Something Awful goons, with a strict no-creepy-stuff rule that included anything furry, and one of the mods recently started a furry thread in the off-topic section that's turned out quite friendly so far.

It's so utterly, utterly true though.
