Stupidity isn't the issue. It's a willingness to believe propaganda and/or an unwillingness to research for oneself, or to believe anything that challenges one's (MSM-generated) beliefs, but that is not a reflection of mere IQ.

This is about deeper issues, like an emotional need to belong and be accepted, and these issues are easily exploited by the MSM/DS who are very adept at manipulating people through their emotional weaknesses.

Also, there are other factors that make some people less vulnerable to deception. I would be very interested to know the relative television watching habits of sheep vs patriots To me, tv is a constant bombardment of mind-control tactics (with MSM newspapers following close behind). What is it that makes some people able to see that and avoid tv while others turn to it like heroin?

There may even be genetic factors. (I have actually heard it said that Rh- people are harder to manipulate.) But it's definitely not about stupidity. It's about an inability (or perceived inability) to think for oneself and to act on one's own convictions regardless of what everyone else is doing. Patriots have the confidence and courage to do that; normies apparently don't, regardless of how smart they are.
