Geopolitics/politics - that’s debatable. Those things effects business and our lives in the long run.

As for highly controversial - I would have agreed until last week, when I saw bunch of people, saying, that sexism isn’t big of an issue in workplace - and that was few days after one CEO, whos known for sexual abuse, was blantout sexist and homophobic on national TV. You can just imagine what kind of environment is to work there - and IMO it’s beneficial to everyone to discuss that, so people can easier decide wherever they can work at particular workplace
