Alrighty y'all, Lua is adding her two cents worth here.
First off, being brony isn't something that makes you less "manly" in all honesty a guys manliness isn't measured by his "likes" and "dislikes" in my opinion. As a woman, I honestly judge a guy's "manliness" on his integrity, honesty, and whether or not he will be there for the people he cares about.
Also, my brother is a wrestler, and plays football, but he watches MLP. Does that make him "un-manly"?
Not trying to seem mean here, just saying y'all, a fandom does change you as a person, nor should it effect things like "manliness".
Also, i agree with Chronic, we're all furry here to some extent. So let's chill out, and just be happy. Brony's and furs, and humans, or whatever you are, we gotta come together. I mean furry doesn't have a good reputation to start with, shouldn't we channel our energy into fixing that before we start arguing amongst ourselves?
