I won't say who on the public GC board, but we had and we still have male cops too.

This isn't a gender dependent thing.

What is gender dependent to a statistically significant degree is that posters who introduce themselves as female are much more accused by others of being cops or "civilian" antis than posters introducing as males do; and that while I know of no male poster ever self outing just to prove their own authenticity; I know of female posters doing that, including underage girls who thus became de facto martyrs for our common cause.
