It's important to realize where doomer culture came from. It largely began as a response to feel good messages which were decorating the truth of things at the benefit of no one.

The main issue being, doomer culture can be embraced as a way to accept things that are beyond your power and double efforts on what you can change, or as a way to toss away all efforts and be in a perpetual state of not caring. It also serves as a counter to society continuing to polish turds.
