I believe in freedom of expression as long as such expression is not designed/delivered to incite hate or advocates violence, controlling others etc. I have a lot of conservative friends. I don't mind if they think I'm being sinful, un-Christian, you name it and i see a lot of it on facebook, they are entitled to think and express that.
Continual hate speech though, drives people to violence and it becomes a life or death thing for many people. Society will eventually dampen such viewpoints as it has with to some degree with racism, sexism, homophobia, etc., but it never fully goes away.
When i hear quasi-hate speech, like the "Lgtb agenda is destroying our nation" it reminds me of the same sort of talk that preluded lynching, mass discrimination and even the holocaust. There is no place for that sort of discourse in public. People are easily manipulated with fear and hate and the purveyors of it know that very well. Societal pressure at every level is a check against such plans.
Instead of giving any time to ridiculous things like bathroom usage, why isn't society debating about poverty, how to drive peace, dampening of extremism, reducing inequality, reducing environmental danger, and dealing with a record incarcerated population? Those things could have multi-sided solutions and debate, but for some reason except perhaps in election years, you hear very little about it.
