You cannot reason with an irrational person. They are operating under an internal logic that makes sense to them. The opposite of irrationality is not reason, it is force.
Think of every liberal ‘educating’ you about anything and everything you do wrong, with a haughty look, open mouth, and a raised pointing index finger.
The many stupid among us cower, listen, and get lectured. The only sane response is a raised middle finger, or two.
You cannot reason with an irrational person.

The Left, by and large, are emotion driven creatures. Facts, logic and the lessons of history mean nothing to them.
You are correct. Attempting to have a rational, constructive dialogue with them is futile.
