https://www.astralcodexten.com/p/if-its-worth-your-time-to-l... elucidates this argument very clearly:

> People don’t like nitpickers. “He literally did the WELL AKTUALLY!” If you say Joe Criminal committed ten murders and five rapes, and I object that it was actually only six murders and two rapes, then why am I “defending” Joe Criminal?

> Because if it’s worth your time to lie, it’s worth my time to correct it.

> If one side lies to make all of their arguments sound 5% stronger, then over long enough it adds up. Unless they want to be left behind, the other side has to make all of their arguments 5% stronger too. Then there’s a new baseline - why not 10%? Why not 20%? This mechanism might sound theoretical when I describe it this way, but go to any space where corrections are discouraged, and you will see exactly this.

Damn, the racism example is really good.
