There is a pressing need for a mercenary bouncer organization, with three or four degrees of separation from the celebrities they are protecting.
That is, the celebrity (likely conservative), takes out an annual “newsletter subscription” for $500-$1000, and yes, there are some newsletters that cost that much. In exchange, the Merc Bouncer organization sends a few tough guys to a celebrities’ performances or public appearance.
When fruitcakes pop out of the audience to assail the celebrity, a bouncer does a quick MMA take down, perhaps breaking fingers & toes, an arm or a kneecap. Then they drag them out to the street and leave.
Conservative speakers on college campuses could use that service.
