And/or did the government decide to push their politics and religion on Hobby Lobby via their healthcare legislation?
(edit: not endorsing either the government's position, just saying that yes, government is exactly where we see politics being forced on things)
I accept, though, that corporations are artificial constructs that exist (ostensibly) to benefit humans, and therefore placing restrictions and duties on corporations is inherently preferable to placing them on humans themselves.
Elsewhere in the thread, you call these "Europe good, USA bad" points. I certainly don't think that's intrinsically true. It's just a different interface that puts more choices in the hands of employers instead of government. A side effect is that employers are going to get judged by employees, investors , customers and the public about how they make those choices.
The issue is that when someone says "let's stay away from politics", it's pedantic and obtuse to start listing things that in some way involve politics.
It's clear what they meant: the more something is related to politics and unrelated to work, the more we should try to avoid it.
Your response does the exact opposite of that, bringing up a bunch of hot-button political issues tenuously related to work, which is a great way to bring more conflict about politics into the workplace.
My list was about how the US has more issues requiring good faith discussion, which certainly opens the door to bad faith as well.
As far as using "let's stay away from politics" as a magic wand to shut down a topic, you are expecting people to agree with you about what belongs at work without discussion or judgement. I think companies and individuals can make things more efficient by clearly articulating a mission, and by proactively taking a stance about how hot-button issues relate to that mission or not. But nothing is going to exempt you from judgement when people disagree, and there's always the chance that you really are the bad guy. That's life with other humans.
