“have been the main beneficiaries of Charlie’s murder”
That is a fact.
Charlie Kirk was trying to hold “the big tent” together as best he could—and he was generally successful in that effort.
As to conspiracy theories about his assassination—I have no clue. To date I have been unconvinced by the various claims out there in the Wild West of the Web.
Yep, I have no proof either, but it’s curious that I never heard of Nick Fuentes before the murder.
That "big tent" that Charlie was trying to build did not include Fuentes and his ilk. He actually excluded Fuentes and his supporters from his events.
There is a Grand Canyon-wide gulf between what Charlie Kirk represented, and what Nick Fuentes is. Republicans should hammer than difference and make sure it is clearly understood by everyone.
