Rosa Parks really should have just sat down in the right spot on the bus instead of shoving her politics in people's faces. There's a time and place for activism but it's definitely not the bus – I have to use it to get to work!
Political activism is not effective unless it inconveniences people, because otherwise people can freely ignore it and sequester it as something they don't have to care about.
If you insist on people bringing politics into work, you will open the floodgates to so many problems. And just because some group of activists is supported by management doesn’t mean it will always be the case, and you’re just supporting workplace bullying then of those who do not wish to conform to the activist culture.
Business and professionalism concerns would make it expedient to avoid bringing political conflicts into the workplace.
There is plenty of time to organize, advocate, etc without inflaming the workplace and creating a toxic environment.
It's like going to a Wendy's and instead of asking "how much for the burger" you start a conversation like "I am bald. Do you like bald people? Is this Wendy's aware of bald people existence? Do you recognize us as people? Do you stand by our side or not?"
Then you review the Wendy's: "Did not speak my language. Not bald. Probably racist. Won't come again."
