You don't have to concede anything. No one ever does anyway.
The fact that this is a courtroom or a Lemmy comment thread doesn't somehow negate the accuracy of the language being used. The context doesn't change what the words mean.
And frankly, there's nothing for you to concede. You've already admitted that I'm right and you're wrong. Your only remaining argument is apparently that because this isn't a courtroom, I'm somehow wrong—which is some impressive mental gymnastics.
"You're right in the only place where it matters, therefore you're wrong here."
Okay. You said some stupid-ass shit, got called out on it, couldn't come up with a response for weeks, and what you've finally come up with is still bullshit.
Don't worry about it. I got you.
Thanks for admitting you were wrong.
