I don't think politics should be discussed at workplaces that do not participate in political systems in an official capacity (lobbying, PACs etc.). If your employer engages in politics, then that should be an allowed topic and/or other accommodations should be made for employees who regard their employer as morally reprehensible.

I don't consider these political in any way. Employees should be able to talk about how the company can improve its own diversity policies, irrespective of what the government decides what to do. The line of thinking here is similar to "separating church and state," and also that it's easier to change company policy: changing company policy provides quick and "easy" improvements to social progress, while the longer and more difficult fights at the political level occur.
