I know it's due to the whole transgender issue, but I see it on Facebook that men should NOT be able to go into the women's bathroom.

Ok.

But what about women going into the men's bathroom? You NEVER see complaints about this. If this is about keeping the people in their "correct" bathroom for their gender, shouldn't these women be complaining about keeping everyone in the "correct" bathroom?

On another note, I have seen women barge into the men's bathroom many times in the past in bars and such. And this was A-OK? I've never heard women complaining about that before, but if a man goes into the women's bathroom at a bar I bet he'd be arrested and labelled a sex offender.
