mule

In the brony fandom, “mule” is a derogatory term used to refer to a member who is equally or more involved in other communities, especially rival groups like furries and weebs. This often demonstrates a lack of loyalty or understanding of pony identity.
The term is derived from the fact that mules are sterile offspring of a horse and a donkey, and even in MLP:FiM has been used in a pejorative way.
Not all bronies and pegasisters with separate interests and hobbies are considered mules, as long as these do not conflict with the customs, ideals, and purposes of the herd.

How are we supposed to consolidate as a strong and committed community with so many mules these days?
