Please be aware that people who say this is unfair (in sports) aren't saying trans people aren't allowed to be who they are. I am against trans women competing in women's sports, especially those who transitioned late in their life. But that doesn't mean I'm against trans people.
I don't mind the whole bathroom thing. Poop where you want, everybody poops. And conservatives will always find a reason to be against anything that goes against their norms. You might find that the backlash is getting worse, but actually it isn't. More people than ever are accepting of all things LGBT, conservatives have just become more vocal exactly because they are becoming a minority.
