That feels to me a little like someone telling me "We both agree that this person is currently a slave, so let's not allow your heartfelt belief that slavery is immoral interfere with our use of this slave. Moving on."
And I imagine I will regret saying that, but I can't see letting that stand and saying nothing.
No. It is actually one person saying, that's a slave, and you responding, no you are wrong, that's a slave, and you are wrong because we disagree about slavery.
Hsu said there was a ceiling on the test, you said he was wrong, there was a ceiling on the test, and IQ is flawed.
