The problem is the idea that you can't be above the fray. It's clearly false as a literal claim - I've never met anyone who struggles to avoid discussing communism with their coworkers from China or Modi with their coworkers from India. In practice, whenever I've seen people say that it's impossible to be above the fray, what they mean is that suchandsuch issues are very important so they think everyone ought to be dragged into the fray.
Yeah. There needs to be a middle ground. Terrible things are happening around the world, and nobody has the time or energy to attend to all of them. On the other hand, if somebody is calling a co-worker some racist term, looking aside is pretty cowardly. Everybody should probably think this through for themselves and figure out what they can live with.
