Do you agree with this quote?

I'll ask again: in the scenario that I'm talking about, where nobody at the table is interested in the art of debate, do you think that it's morally acceptable for the nine to be friends with a Nazi?

"friends"?  Where is that in the quote?  It's not even implied (or inferred?).  I've sat at tables and was not friends with everyone there.  Hell, I've sat at a table with people I've hated before.  It didn't make me whatever political label best describes them.  If you put the label of other groups in the quote, do you come to the same conclusion?

"If there are nine people and one used car salesman sitting at a table, there are ten used car salesmen sitting at a table."

"If there are nine people and one Commie sitting at a table, there are ten Commies sitting at a table."

"If there are nine people and one Cop sitting at a table, there are ten Cops sitting at a table."

It's implicit in the intended meaning of the statement. Don't be deliberately obtuse about this.

You are using "sitting at a table" way too literally. It's very obviously meant to be people you are friends with/willingly associate with.

Why else would the author have come up with the quote in the first place?

of the 17 people to read this so far, you're the only one to come to that conclusion
