Okay, genius; Riddle me this....
* The "decayed" societies you abhor tend to be these shining, stable, prosperous places with a good economy, high standard of living, long life spans, low child mortality rates, better medicine and hygiene, less crime and dysfunction.
* The "righteous" societies you'd prefer, where colorphobia, ethnicism, misogyny, toxic masculinity and homophobia are rife tend to be these dumps that are the exact opposite.
....Now; Explain how the former is decayed while the latter is healthy, Mr. Bizarroworld.
[This is all the more reason I think that bigots and reactionaries see a crapsack world as a good thing rather than bad. It's easier to get followers to control when they are desperate and they figure a hard life makes you "strong" or something.]
