Lesson of the day - if you want to set up a 501(c)(3), don't be a pedophile
and a convicted felon. I do have to wonder if scientific research into human-animal hybrids is counter to public policy, though.
It's also fun to consider how many ways furry cons have "more than insubstantial non-exempt purposes". FC, MFF, FurFright and Rocky Mountain Fur Con are run by 501(c)(3)s. (Furtopia also claims to be, though I'm not sure if
this is it . . .)
