The problem seems to be people who conflate 'Trans' and 'Pervert'. My wife's parents hold the view that Trans women, because of their male birth-gender, are likely to sexually harass young girls in public toilets, and they cannot be persuaded otherwise.

Creepy men will be creepy men, irrespective of which toilet they go into - I've met a number of creepy men, been propositioned (and, on one occasion when I was mid-teens, sexually assaulted) by creepy men in male toilets. Steve is on the button regarding the use of public toilets - wherever possible, take steps at home to avoid needing to use them, but if use of a public loo becomes necessary, try to use a busy one. Every time I've had a problem with creepy men in a public loo, it was in one in which we were the only two using the facility.

I would be far more concerned for a trans woman who was obliged to use a male toilet than I would be for other women and girls with a trans gender woman using a women's toilet.

Trans people are not perverts. They are people living in a personal hell, who have taken an immensely brave decision to make a huge change to their own lives which many self-styled 'normal' people cannot begin to conceive of.

And Steve's absolutely right about dirty buggers who take a leak or a crap and don't wash their hands.
