It’s the “through and through” part that kills me. It’s just such an ignorant statement.
Lawyer/NLP trick. State the most absurd and offensive part of your argument loudly and defiantly, and the weak listener's mind will go into acceptance mode, because of the intense level of cognitive dissonance created by your assertion of the impossible and revolting.
A healthy mind, on the other hand, respond with scorn and rejection. Which is exactly why liberals are taught not to be "negative" - so they can never have a healthy response to leftist insanity.
Of course it’s ignorant, but it’s also delusional. It implies a detachment from reality.
