Several comments on here read like prime examples of “anyone who opposes me is a fascist”. Of course in conservative forums it’s similarly “anyone who opposes me is a lunatic Marxist”. Try having a relationship across aisles in this climate!
The study took 30 years to conclude but I wonder whether the current political climate makes it even more unlikely that people across political divides can form really any kind of relationship. I know I have found it difficult to maintain a relationship with anyone staunchly conservative even if political leaning has never been a main criterion for me in mate selection or in friendships.
