Just another delusion that they lap up like mothers milk.
What I’ve seen with most of the leftists in my family is they take fake news/main stream media to heart.
They believe all of the CNN/ABC/CBS/FB..etc stories. They almost as automatically doubt what any right wing source says or at least are skeptical.
When you prove a point, even a simple one (like 1 hour ago I showed a fact check to my liberal son in law that inflation is NOT caused by corporate greed), they are genuinely surprised.
In other words they have horse blinders on, can only see straight ahead of them.
