How about instead of dumb I say ignorant? A lot of these people, Shapiro, Trump, Charlie Kirk, etc. have far too many followers that seem to be very ignorant. They go on and on about freedom but only the freedom they believe in.
They want everyone to be Christian and rail against other religions. They would much prefer if you were white. The want people to live their lives based on the bible, well the parts of the bible they are with. They tend to be anti-science. The go on and on about cancel culture even though they are the experts and try and "cancel" people or companies all the time. The one of the big ones if violence, they tend to be much more approving of violence than the general population and this has been show to be true in study after study.
Shapiro believes "Western civilization" is superior than all others. He has a low view of women and this includes limiting reproductive rights like abortion EVEN in cases of incest and rape. He argues anything under the LGBTQ+ umbrella is a mental illness including trans people.
So the guy might be educated, he has a Harvard Law degree, it does not preclude him from being ignorant and on the wrong side of most of these issues.
