I agree.
Around the 11 min mark he says If we are gonna call him crazy and angry then you had better call everybody on the news from 4-12 crazy. Hmmmm did he and his brother watch the news together? Not one of those reporters thought to follow up with “what kind of things annoyed your brother?”
That is telling, when grasping for comparisons of his brother’s state, what top of mind for the brother? What’s the very first comparison draw? => People on the news from 4 to 12 pm. If his brother is crazy, then the people on the news are crazy.
Suggests political rants were common with his brother.
And, himself, we agrees with those rants more than he disagrees. That’s what he’s not telling us.
