Man, after seeing so many discussions on identity politics, many of which were on Hubski, this definitely rings true to me. I have no damn clue whether this had any impact on the US presidential election, but it's a problem either way. The fact that there's a contingent on the left that's ready to publicly criticize Bernie freakin' Sanders of all people for not doing enough means that there's a major problem with identity politics in this country. There is far too much "no we can't have a conversation, you need to shut up so I can educate you" going around in the far left. I can't think of anything more closed-minded than that. Yes, it's 2016, and you think that you shouldn't have to deal with this anymore, but can we at least have a two-way conversation?
What's worse is that many of these people, who come from the far left, act like they have the strength of a large majority behind them, as if all decent people were all highly educated on all of the proper pronouns, politically correct terms for disabilities, things that come after T in LGBT, etc. Honestly, I'm someone who tries to make an effort to keep up with this stuff and call people what they want to be called, and it's quite a lot to remember. What I think is happening is that individual minority groups, who are familiar with their own accepted, politically correct terms, can sometimes forget how many minority groups there are out there, and how divergent the opinions of people even within their own minority group are, so they have no empathy when someone else gets their terms wrong. For example, I've been stuffily corrected by (usually white) academics that the proper term is "African American" even though many black people prefer the term "black," I still don't know what "genderqueer" even is, and I can barely remember that "neurotypical" means "not autistic." And I'm willing to bet that most swing voters are less aware than I am, and are a hell of a lot more alienated than me when they are stigmatized for not keeping up with twenty different kinds of politically correct..
