Link to a recent thread discussing the same issue:

There was a male poster whose responses were particularly illuminating. He berated women for excluding and disadvantaging men, because clearly when we've just given birth that's what we should be thinking about. Then there was thinly veiled whining that women on a forum catering overwhelmingly to women dared to discuss being afraid of assault from men we don't know, insistence that his right to be present would be more important than the comfort and health of patients, and finally a dismissal of the women who didn't want men there by saying they'd just have to manage. And this was one of the ones who wouldn't be kicking off. Those of you who blithely trill that 99% of the men there will behave themselves don't live on this planet.
Also worth a read because it contains links to other pertinent threads and recounting of some hair raising stories.
