> How you made the leap from, "Defending oneself from an accusation inherently entails discrediting the accuser" to, "knowingly lying and needlessly insulting people is okay" is a mystery to me.

Ah, I'm sorry that was unclear.

The word "discrediting" is ambiguous. It's sufficiently general so that it's hard to make a moral statement about it. You can discredit someone by pointing out flaws in their statements. You can discredit someone by lying about them. There are lots of ways to discredit people, so just saying that it's OK to discredit the accuser doesn't really imply any specific moral principle. It's not a useful statement.

Does that help?

Edit: whoa, crap, I missed something. I did not say "the subject at hand did neither of these things." I said "we have not established whether or not Kavanaugh was lying, and I'm not saying he was." Close one there!
