I agree with Bumble....
I think in here you can be refused to a fellowship for any reason, or no reason at all.

Race, creed, color, political beleifs, whatever, if the big boss doesn't want you, you are out, period.

Not sure how one would actually determine this however... My guess is that there are a women or two, who are on this site pretending to be males etc.... how would one actually know?
