Sometimes you get the opposite - LW seen as an SJW forum because Scott Alexander is okay with referring to his partner as ze/zir/zur in his blog and if you are not American, or over 40, or at any rate did not go to a US college in the last 15 years this comes accross as weird. I remember even on Reddit as late as 2009 the "in" "progressive" thing was to hate Bush, not to understand something about transgenderism or feminism or what, so it is a very recent thing, I would say, in mainstream circles.
