The constant hate being spewed by the left is heard by teens and college age students. This in turn brainwashes them to act out in hate.
The cartoon writer of "Dilbert" said this about the constant spewing of hate.
The hate being spewed out towards Christians, America, White men, etc. This leads some to act. Like all the recent transgender shootings of schools, people, etc. The hate doesn't really need anything but social media, the mainstream media, teachers, professors, etc, constantly filling the kids minds with hate for this or that.
Charlie Kirk advocated home schooling to keep the trash out of kids minds.
