if you come off like a jerk, they’re going to be less likely to accept your argument
Very true. Lots of people attempt to package two messages together:
You’re wrong about this
You’re worthless
Quite frankly, people should reject the second message, and people who try to package the first with the second should expect listeners to reject the whole package.
Honestly it’s probably better for people to reject that whole package of messages than to accept it, even if it means being wrong, because at least they won’t be taking that toxicity into their soul.
Someone who goes around trying to convey those messages together, to be accepted as a package, is themselves doing it wrong.
