ERA probably just means "alt-right" with it, but you get bored typing the same thing all the time and have to mix up the terms. It was probably on some site or something, maybe one of their garbage YouTube heroes that they haven't discovered is a hamburger turtle and permabanned yet, they used to always pick up the newest "clever" lingo from some place and repeat it endlessly. Like "clown car" during the primaries.
Or in that woman problems thread when they all suddenly were orgasming over someone "coming up with" the term "brogressive" which had been around the internet for three or four years already. And then they used it in a bunch of threads for like a couple weeks before moving onto James Gunn or whatever literal biggest crisis in world history came along next.
