The left is going through a dying process.
It will never be over. I have lived long enough to see cycles where we have declared final victory, and so have they at different times.
Liberalism is like corrosion in a plane or ship that has to be constantly battled and fought. Once it stops being fought, it gains a foothold and begins to grow anew, winning victories until forces are marshaled to fight it again.
Better to put our foot on the neck of liberalism and keep it there, always, so it can’t surprise us and bite us like the snake in the grass that it is.
