Well, I'd guess around 10-20% of those posting on /b/ happen to be furries, in reality. Possibly a larger portion. Personally, I think those screaming about /b/ being a "furry hating" place are just those that are upset and unreasonably feeling hurt about "fursecution."
However, getting one board to 100,000,000 posts is a pretty big accomplishement; according to
Big-Boards, only nine other boards have accomplished this. (they intentionally do not include 4chan's boards) And all of them have the advantage of being far older than 4Chan, which will be turning what, 6 this year? What's also impressive is that the 100M Get was not just furry, but a nice pic, too... True, the herms and fetish pics may outrage some of the high-schoolers that get on in the evenings more, but what's even better is if you manage to post stuff that actually APPEALS to them and potentially 'convert' them.
