Ethical concerns should be raised at work, but I believe politics at work should be avoided.
There's no such thing as a group of people who agree about politics. They only think they agree until enough details start coming out.
The question is whether these differences are handled respectfully and people learn from each other, or whether they see it as a moral battle and end up hating each other. In the current cultural climate, the latter seems more likely. And I see no benefit from carrying that into the workplace.
