On what basis?

There is just no logic to this argument whatsoever. The proliferation of unisex toilets would inevitably mean more people in any one bathroom at any one time. Which, by all conventional wisdom, thus makes them safer.

And again, if you think that right now, this very minute, with the existing set ups we have - 'perverts and rapists' won't enter toilets that don't correspond to their gender because of a sign above the door, you are sadly mistaken. Also again - you're more likely to be attacked at home than you are in a public toilet.
