This may be a contentious statement given that I am: a) not trans, and b) not living in North Carolina, Mississippi, or Alabama. But I am glad that bathroom bills have brought discrimination and harassment against trans people to national attention.
The fact of the matter is that denying trans people access to public restrooms did not start with bathroom bills. It was already an ongoing problem.
In the last few years, when US marriage equality was imminent, LGBT activists were worried about what would come next. For so long, marriage equality has been the LGBT issue in the US, as perceived by allies and outsiders. Activists themselves knew there were plenty of other issues like employment discrimination, trans healthcare, and de facto health and economic disparities. But if the general public starts to believe queer issues have already been solved, just like they believe for racism and sexism, then activists would run out of steam and funding.
