"Ad hominem: (of an argument or reaction) directed against a person rather than the position they are maintaining: [as adjective]: an ad hominem response." Sounds a perfect fit to me. It's rarely about tackling the position (because I suspect Winters isn't able) but about the man. After all, where's the mercy, charity and accompaniment for Burke? Where's the considered, thoughtful and charitable argumentation to help him see the light and wisdom that Winters is so privileged to possess? Nope, it's almost always ad hominem.
