No. Not to be rude, but that is ridiculous.
Your point is that when you tell someone you're a brony you don't want them to think of you of as a clopper? Hunny, I'm sorry, but no matter what you do, that stereotype is always going to be there and someones always going to go by it.
Why ever should they be seperated? A whole fandom just for the r34 things is simply stupid. There is r34 things and people that can get sexually excited to contents of the show in every fandom, but because My Little Ponies fandom is big doesn't mean we should get privilege of having two seperate fandoms.
The point of 'Love and Tolerate' is to love, care for and accept all. If we do that, that's not whats happening. Those are our ethics, what the fandom grows off, we can't simply throw that away because of something that is everywhere.
Definition of 'Brony' is a person who enjoys the show My Little Pony: Friendship is Magic. Enough so to be in the fandom, no matter what age what gender they may be, a play of words combining 'Bro' and 'Pony'. Definition of 'Clopper' is a brony who gets aroused by ponies and because of it takes action. There can't be separate definitions if a clopper is just another type of brony.
Now, I would write a whole rant right about here, but it's three in the morning, so I'll save my energy
