I read the original post from Brian as; you can, but at work one should work. Coinbase isn't paying folks to debate politics, they're paying someone to further the company mission.
this is undoubtedly true, but also undoubtedly easier said than done. we don't seem to be wired as a species to have difficult conversations without feeling emotions amd having those emotions affect our relationships.
And the people most inclined to discuss politics in the work place tend to be the people who take it personally.
