Facts exist outside of you. Facts are already confirmed/researched and we just call upon them in conversation.
If an argument is based around a fact, there is indeed a right and wrong side. The accuracy of your recall of a given fact is the meaure of rightness in the argument.
How did you get that from what I said?
Here lemme flip the script on you. If you can't listen to someone and absorb information without immediately conjuring negative assumptions about them, you might not be fun to be with either.
The point was that facts are facts. The fact that calamari is not caviar is not malleable (unless you're in Estonia I suppose lol). It's just a cold hard fact that outside of Estonia they're two completely different things. In this situation there is no spectrum of rightness. You're just either right or you're wrong.
I'm not saying that its worth dying on the calamari hill in public. Handle that debate however you see fit.
