A brief thought: I think we need to take a long step back from "irony" culture.
There's a pattern I see repeatedly where people immersed in "irony" seem to not comprehend that other people actually believe what they're saying, because "irony" dictates that THEY don't believe anything they're saying. It's all a joke; it's just "for the lulz", to score laughs and Internet Points.
Being earnest is a completely foreign concept, and so they assume NOBODY is earnest.
