I think it has a lot to do with problem-solving mindsets, and with my friend circles tbh we are all of the notion that disagreement is inevitable but also a learning process and involves basic respect for each others' opinions. Also we kind of all sense that everything is political/connected as-is.
I do think there's a lot of avoidance in society lately but if you want to get along better and understand each others' contexts aka build that friendship, you gotta have that space to debate.
