Tucker Carlson tries to put his finger on the real issue.
According to liberals, it is guns or white supremacy that kills people. Vehicles also kill people like at the Christmas parade in Waukesha. Climate change causes wildfires. Incels also kill people. It is never sick, twisted, evil, nihilistic sociopaths who kill people because of their character.
If you focus on the character of mass shooters, it raises too many uncomfortable questions. They are almost always deeply alienated, lonely, nihilistic men who are suffering from a mental illness. They are often loners who were bullied in school. It is not deeply religious, married men with children who become mass shooters. It is people who are deeply unhappy with few social connections.
Note: I would love to see how mass shootings intersect with loneliness, mental illness and social atomization in advanced liberal societies.
