I find this 'sweep your floors' meme a bit of an oddity:
1. It involves conservatives casting native americans in a good light. Who's going to argue with that?
2. It contains a false epiphany which just feels right (the solution to forest fires is...fires)
3. It contains a grain of truth. Native americans did perform controlled burns, and in the NW they did take care of salmon streams etc, but not on a scale that would prevent today's wildfires.
It's a classic diversion from climate change, and our terrible 'foresty' practices of cutting down forests and planting monocrops of high resin species all packed together and calling it reforestation and finally, spraying entire valleys with roundup (often where indigenous people live of course)
