Summarizing Omeg's excellent post #3028:

The goal of an argument or discussion should not be victory, but
progress.

Convincing yourself does not win an argument.

An argument is the longest distance between two points of view.

If you desire the last word in an argument, try saying, "I guess you're
right."

And for fans of satire - If you lack the ability to answer an argument,
all is not lost; you can still call your opponent vile names.

Empathize. Sympathize. Juxtapose. Concede honorably. Keep dignity.

As always, with best regards, I remain
Very truly yours,
