If it's my personal belief that I am duty bound to try and get this person fired and find legal ways to ruin their life would you be supportive of that? None of this activity would be carried out at work.
I don't discriminate at work, full stop. I don't care what you do or who you screw so long as it doesn't affect folks at work. The second you start pushing your political agenda at work it becomes a problem. It has nothing to do with a "safe space" and in fact it is in no way a safe space. Work is not a place to talk politics and push your ideals onto society. We all know these "safe spaces" are just a place for a given "side" to espouse their ideology without having to defend it from rational discourse.
