That piece doesn't make any sense.
What does being transgendered have to do with loitering around a bathroom? Or homosexuality? Unless the article was actually talking about cisgendered people being in the opposite gendered bathroom claiming they are transgendered as a means to justify their being there in the first place... which isn't the same thing as 'loitering'. That word is inflammatory.
And if homosexuality is a factor in this rather crude and ill-conceived argument, won't they be focusing on entirely the wrong place?
Finally, wouldn't any nefarious individual have to cross dress, before even getting there, in order to even contemplate using such an 'excuse'? Something tells me they wouldn't like the attention.
Here's to rational thought... and obvious lack thereof.
