Nothing about what I said means that values are static over time or that the balance can't shift. It's true that today's crazies at the edge might be tomorrows center - although I find that thought troubling!
But make no mistake, the extremes at both ends harbor dangerous crazies. In politics, while the evils of the right are obvious and dangerous, the evils of the left are much more seductive but have been just as dangerous this past century (think fascists vs communists).
On gender issues, the incels are clearly unhinged. But so are the extreme feminists.
