I guess I should have realized there's no reasoning with a Leftist.
Not from your perspective. If your platform revolves around fantasies and is completely bereft of any data or critical analysis, don't be surprised when 'Leftists' call you on it.
Why am I always so astonished at the stupidity of the Left?
You believe in fairy tales. My guess is you are astonished by things you do not understand and then label them 'stupid' because of your lack of fundamental understanding. Reminds me of how young children behave actually.
'You're stupid!' was a common insult evoked by young children in elementary school. Along with the 'I know you are but what am I' tactic. I am surprised you actually haven't used that one yet. Although I don't read all your posts, so maybe I missed it.
