I'm 52. For me, there was a time when it was considered impolite to talk about sex, religion and politics. Then it became super fun when done with open/questioning/rational/critical minds, and a lot of progress in my own thinking was achieved from the usually non-threatening but lively debates and fights among friends and family for ideas. Then it shifted in the last ten or fifteen years. When social media started having friends of friends, the tribalism kicked in. It was explained very well in a talk between Maria Ressa and Jon Stewart. She is brilliant, and well worth listening to. https://www.youtube.com/watch?v=jsHoX9ZpA_M
