The average Liberal supporter just does not live in reality with the rest of us. They exist in a carefully curated info-bubble and can easily refuse to believe facts and logic if it competes with their own internal narrative.
Sargon of Applebee's calls it a Hyper-Reality
The progressive hyper-reality trumps our reality so it doesn't matter what you tell these people nothing they see makes even the smallest dent in their belief. They know the "truth" and everything else is just wrong, they don't just know it, they feel it down to their very bones.
Oddly enough it's the progressive Left, and not the conservative Right, that turned into a group of religious zealots. Ready and eager to burn any heretic or non-believe with a unshakable faith in the system.
It's fucking bizarre but it also show how far the progressive have move the Overtone Window that a huge swath of the Western World can look at a picture, or a video or a scientific report and see the exact opposite of what it says and be 100% that what they see it correct. Reality really is what ever a progressive wants it to be and they will outright refuse to see the truth even it if kills them.
It's insanity, pure insanity and it's swallowed like 60% of Canadians whole.
