The fifty cent word for this is cognitive dissonance. Lab rats do this when some external input begins to interfere with their prior conditioning.
I get the whole cognitive dissonance thing. It’s the INTOLERANCE that aggravates me.
We’re polite to them, they scream at us that we’re murderers.
We oppose tax cuts, they encourage abortion and call us murderers.
We oppose socialism, they encourage abortion, cheer on child molesters and call us murderers.
We oppose govt run health care, they encourage abortion, cheer on child molesters, want to give cyanide to the elderly and call us murderers.
You see what I mean?
