Leftists have no grasp of fundamental biology. If they did, they'd understand that poisoning the well yields resistant strains of the very thing they want to kill - which in their case involves conservative thought. They'd love to kill off any disagreement with their views, warped as their views may be.
What they don't understand is that continually calling other people racists, bigots, and an assortment of other names - which is their trademarked approach to discourse - accomplishes little. Some people may shy away from the branding; others derive strength from it. We're like superbugs that developed resistance due to chronic misuse of antibiotics.
Bring it on; we're not going anywhere. Scream, holler, break stuff, call people names, go "on strike" and so on; we thrive on the tantrums. We're "RoundUp Ready", and immune to their poison.
