That's the thing. Although to me he is not charismatic in the slightest, I'm also not his target audience.
Young boys who don't have a lot at home could see him and his lifestyle and think "yeah he's right, look how successful he is!" and then fall further down the rabbit hole. Never mind what that lifestyle is built from. Once he's groomed them to an acceptable level they blindly scream about how he's being framed for talking about x or y so the establishment is against him.
He is a massive danger to the young and impressionable.
