Describing a set of societies that featured large scale human sacrifice as in any way communal or egalitarian is bordering on deranged. Even examining them purely economically, they were often heavily based on extracting and centralizing resources from weaker communities subjugated through violence.
In the course of these comments you've referred to me as deranged and laughable. I'm going to bow out and let you hold onto your opinions, it's clear you're not interested in a conversation.
Declaring that strident criticism of an opinion or perspective is the same as a personal attack on the person who holds it is your assumption, not mine. Good, kind, intelligent people have objectively wrong opinions all the time. This kind of fragility is why The Coddling of the American Mind ended up getting written.
So first, you didn't call the comments "objectively wrong" you called them deranged.
Deranged:
1) Disordered; especially, disordered in mind; crazy; insane.
2) disturbed or upset, especially mentally
3) insane
It's not "my assumption," that it's a personal attack, it's the english language. An idea can't be disordered in mind, disturbed mentally, or insane. Only a person can be.
Second, go back and reread your comments and omit the derision. It adds nothing at all to your argument, in fact, it's much more compelling without it.
I just don't care enough to argue with you about the meaning of "communal" to try and change your mind. Your language choices clearly signal me that you're not open to changing your mind. Instead it signals that you're more interested in dunking than engaging. The Coddling of the American Mind is not about hacker news or my personal choice to ignore you for being rude. It's about institutions. If you want a more relevant book to this conversation, I'd suggest How To Win Friends and Influence People or The Elements of Rhetoric -- How to Write and Speak Clearly and Persuasively.
