OP was asking about respected leaders who are bad people.

Someone responded to that to say Thomas Jefferson.

Then someone responded to that saying "WW might disagree." Meaning: WW thought TJ was a good person.

Then you responded to that with: "Why does one guys opinions outweigh all the other biographies I have read of him." Your statement, of "one guy" refers to WW because that is the only "one guy" identified in the post responded to. Meaning, it looked like you were attacking WW's opinion of TJ based on other biographies you read.
