Netflix and video games don’t directly promote tribal bullshit, and they generally don’t infect the workplace with career-impacting social expectations. I have seen the latter in various workplaces, indeed nearly all of my prior workplaces. The former is just patently true.
I’ll believe this when I see riots in the streets where the local clan win a championship, and/or when spectators with no relationship to the players routinely come to blows over which clan is better.
