Once upon a time I had the belief that such people were merely lacking information. Maybe that they were a little lacking in empathy, but that their positions were primarily a matter of poor exposure to ideas.
I now that though for some that is true, for the overwhelming majority it is not. They back authoritarian views in full understanding of what that entails for their fellow humans, and they like it.
How able are you to evade political violence should it come to your area? Could you get involved with mutual support/defense groups, or form one? People like your team member get away with a lot within civil society, but come asunder should stuff kick off and norms come under strain.
Meantime, be good to yourself. You're far from alone.
