"What "reactionary" movements existed in tribal societies devoid of distinct classes?"
tribal societies specifically?
exactly how far are you narrowing societies you want examples of reactionary movements in down to?
like you want a specific century and a specific type of society? instead of just any non-capitalist society?
how are you defining capitalism?
are you ignoring the contemporary Amish and other people who oppose change out of principle for no capitalist reason?
"I blame Capitalism for Capitalism's issues, not literally everything. "
you're lumping conservative human behavior that exists independent of capitalism with actual examples of direct capitalist problems like mortgage crises.
your brush is too broad.
"I have no idea what point you're actually making. "
yelling "socialism is the best and capitalism causes all the problems" at the people yelling "capitalism is the best and socialism causes all the problems" isn't exactly dignifying your stance with a sense of legitimacy.
