As a SM I try to promote great environement for my team by encouraging collaboration and teamwork. It works well for the work hours, but during lunch time 2 of them always argue against each other on political matters, which tend to deteriorate the mood of the whole team.
Is this something that the SM should solve by himself or is it beyond my role? I know the theory around solving conflict by creating a shared identity. But they are extreme in their view and belief, and I can't see a shared ground here.
