If your favorite Pokemon is one commonly associated with furshit (Lucario, Gardevoir, Lopunny, etc etc..), it is extremely hard to find "good company" in the community. Sure, you could just primarily associate yourself with people similar to you, but that doesn't work sometimes. Some people have "dignity", and don't want to be mistakenly labeled as a furfag. So they'll either get a "new favorite pokemon" or simply never mention what their favorite is.
Same thing applies to say, a Pokemon that is overtly extremely popular. If someone says their favorite pokemon is Greninja, people would be quick to assume that person is either an anime-obsessive faggot, or a smogon faggot. There's a good chance that neither of those are correct, but people will still assume the worst of that person simply based off their favorites.
So, some people selectively choose what to and what not to like, based off the ridicule (or lack there of) that they would get for openly stating their love for a certain "thing".
