>If your boss (or their boss, or their boss, etc.) makes it clear they don't support that: that's not a political statement, it's workplace discrimination / harassment.

I am going to speak plainly. I don't think people in the Valley really believe this argument. Political opinion is a protected class in California yet people feel free to create a hostile work environment for Trump supporters. It feels like there a set of right answers and you can say the right answers or shut up.
