Attitudes need to change.  Men use women's washrooms when the men's are over capacity  (not frequent) and women use the men's washrooms when the women's washrooms are over capacity in most of Europe - the only people to get fussed are the north Americans..  TG people are not doing this to get their kicks. And my personal observation is that people who are the most vocal against LGBTQ community are the most insecure about their own sexuality.
