That there's any cultural "degenerative debauchery" is an extraordinary claim. Can you back up this claim with evidence?
"Decimated," "muddled," and "polluted" imply you have an objective analysis framework for culture. Typically people who study culture avoid moralizing like this because one very quickly ends up looking very foolish. What do you know that the anthropologists and sociologists don't, to where you use these terms so freely?
If I seem aggressive, it's because I'm quite tired of vague handwaving around "degeneracy" and identity politics. Too often these conversations are completely presumptive.
