You literally said exactly that:
The Nixon impeachment was based upon the criminal Watergate incident, so yes, it was a criminal proceeding.
Only in your own mind buttercup. Keep stretching for any warped semantic interpretation you can manage.
No that's literally what you said. He quoted you directly.
Sorry but you don't get to reinterpret my words and then demand I defend your interpretation of them. I said what I said, not what you said I said.
You said "The Nixon impeachment was based upon the criminal Watergate incident, so yes, it was a criminal proceeding."
You can keep saying you didn't, but you did.
You probably just didn't know what a criminal proceeding was at the time, or weren't familiar with the first article of the constitution. This doesn't make you stupid - so just chill out and stop trying to insist you weren't wrong or you didn't say that. We all have eyes and a brain, you aren't fooling anyone.
