Class warfare, race warfare, gender warfare, generational warfare, it’s all straight out of how to bring down a nation. Divide and conquer works. Separate people into exclusive groups, set them at each others throats and you can take over. The traitor within.
It’s, to coin a term (/sarc), Identity Politics.
The problem is that divide and conquor relies on the “conquor” part being feasible. I don’t think it is: I think that the forces involved are too large and when set loose will be unmanageable and will turn on one another. The result is (to coin another term /sarc) Balkanization.
