I think this is missing the thrust of the issue which is that is, for some groups, certain kinds of politics invariably involve work and are a moral imperative.
If this were about issues likee 'big vs. small government' then it wouldn't be a problem.
But it's about political issues like 'diversity in the workplace' and 'Corporate support for Social Justice' (such as BLM) - as the big Elephant in the Room subject.
So things like 'Thanksgiving is Covert White Supremacy' as part of your job training [1] and 'we must achieve certain diversity targets or we are racist'.
That kind of stuff.
There's a group (part of the 13%) that thinks unless you're on board all of that, you're a problem, basically it's a moral imperative and anything else is racism. There's other groups that believe in some of those things, but are open minded with respect to other's views. And of course a wide array of other opinions.
I really don't believe that most other political subjects are entirely so sensitive. 'Privatization of Amtrack' or whatever is simply not going to engender in/out groups.
Abortion, Gun Rights are probably trigger issues for some, but they are really easy to just avoid at the office.
