When have they not gone hand in hand?
Rogressivism has always been a cancer but there was a time when not all was cancerous. Cultural Marxism basically began with the goal of fostering dry rot in the nation’s bones on behalf of the Soviets but even they could not anticipate where the trajectory would take them. Basically starting out as too traitorous to trust they have of their own accord become too stupid to live. But it did not come upon them all at once because if it had they might have jumped out of the frying pan.
“Progressivism” ... I hate typos.
