I find it a bit strange (just the fact that memes have become hardwired into our way of communicating/coping), but I relate to a lot of it. I think subcultures like this sometimes end up romanticizing a depression and hopelessness when there's nothing romantic about it, and people wear titles like "doomer" like a passing fashion trend which is silly to me. But that doesn't mean there isn't any reality to it. Classifications like this just seem to naturally arrive--it's just way to define the temperament of a generation or particular sub-group. I imagine it can provide some solace/solidarity for people who feel isolated and hopeless. Don't see anything wrong with that aspect of the "doomer" subculture.
