Trump just did something that uniquely pissed me off, even though it’s the type of thing that goes completely unnoticed by the media.

Because it’s the kind of thing that no one really talks about.

But in his press conference where he gave away medical information that wasn’t his to give, and embarrassed Mike Johnson in the process, he also used a nonverbal communication that I’ve seen at least 10,000 times before as a liberal guy in a red state.

It’s dominance signaling, and it’s at the core of the Republican identity.
