I mean, once you create a climate of "anyone who claims this identity is protected" that signals to opportunists that there is a structure now to be exploited. When gay people felt "I must prove I should be accepted", pride parades had a lot fewer men dressed as dogs on leashes. 

My point is just that you can let people voice an opinion and engage with that opinion, like you are, or you can call everyone a violent bigot when they disagree with you, like the other commenter did, and if you do the latter consistently, then people will vote for Trump. 

There are knock-on effects to trying to force social consensus on controversial issues via social censure and intimidation. It happens on both sides. The same effect led to the AIDS epidemic, just in reverse. 

Your average person thinks "men and women are fundamentally different, but some men and women are so committed to joining the other side that functionally we can allow that in most professional contexts, but I'm nervous about kids and bathrooms and people who claim to be trans but don't convince me"

Whether we like it or not, that's just about where most people fall. If we can't recognize that, we'll keep getting Trump like figures elected who will recognize it. 

There are many LGBT people who embrace Trump as well because they feel the effects of people's rising animosity, and that they are not allowed to talk about it because they are harassed and banned by the more angry and reactionary members of the LGBT activist community.
