One of the things Emerson was warning about was Dogma:
“The objection to conforming to usages that have become dead to you is, that it scatters your force. It loses your time and blurs the impression of your character. If you maintain a dead church, contribute to a dead Bible-society, vote with a great party either for the government or against it, spread your table like base housekeepers, under all these screens I have difficulty to detect the precise man you are.And, of course, so much force is withdrawn from your proper life. But do your work, and I shall know you. Do your work, and you shall reinforce yourself. A man must consider what a blindman's-buff is this game of conformity. If I know your sect, I anticipate your argument. I hear a preacher announce for his text and topic the expediency of one of the institutions of his church.”
"If I know your sect, I anticipate your argument."
Put in modern terms, it virtually defines the combination of politics, marketing and labeling that defines our current system in the US.
We no longer discuss issues, we anticipate the version of the argument we're told to expect from the assumed "sect" and prepare a response to that. You can see this play out on Facebook or other platforms when you try to discuss an issue with someone and get a response completely unrelated to anything you just said.
Slap a label on a straw man, then campaign against that.
