I'm not sure the premise is true.

Dartford - mixed gender organisers
Good Intent - Big Growly Simon (not female)
Maidstone - mixed gender organisers, I think male majority
Riverside - ditto (I think)
Greyhound - Big Growly Simon.
Moore or Less - Derek Moore
Daz and Man's club also at the Three Mariners - mixed gender organisers (balanced, I think)

That's about as far as I travel.
