After thinking about it a little more, what I wrote above is false.
When a place like CA, NY, NJ, CT or VA persists in passing ever more oppressive gun control laws, the only actual effect is to cause gun owners to decide they've had enough and find a red state to move to. The end result is nothing more or less than the disenfranchisement, as far as has any effect in that jurisdiction, of people who more likely than not hold a conservative viewpoint.
If being a gun owner (and for present purposes, "gun owner" is actually a functional proxy for "conservative") was a religious faith or an ethnicity, the radical left's policies would fit definitions of ethnic cleansing.
