Eh, as far as I see it, people don't really mind furries, its just that they don't know much about them, if anything.
Some people think we're weird, or crazy and some don't really have a problem with it at all. Its just who you meet.
But IF it became mainstream, then it would be kinda a win/lose situation, because yea, we'd have MANY more people bashing us, and belittling us, but there would be much more knowledge about us and after awhile, most of the stereotyping would die down, and we could be considered as "normal".
That, and more furs would be bound to show up. Some of them would be for real, and others would be posers, but who can stop someone from being fake?
