But if the football player interrupts the game and starts running around with a BLM flag in the middle of a play, that's inappropriate. Or if my manager decides to use the first 5 minutes of every standup to have a group discussion about libertarian ethics.
There's no bright line between which speech is appropriate and which in inappropriate and it's all subjective; and I would certainly oppose any sort of legislation that impinges on the expression of free speech in this area. Society can negotiate these rules in the course of social etiquette, not in the court of law.
But c'mon, when we're at work we're here to get shit done, just let us focus on that. If a group of coworkers wants to organize around common political goals, do it amongst yourselves. Go ahead and use a conference room and work laptops even, if it's after hours and not disrupting business.
Much of the discussion here today is confused by the intermingling of so many concepts under the singular term "politics".
