I was trying to think of a comment you literally can't disagree on. I figured it out.
The comment goes as such:
"If you agree to this comment then you agree to this comment"
Because if you disagree then you don't agree to that comment making the comment correct and agreeing.
Stuff like "The sun is sunny" can be disagreed upon but my comment can't.
Also, there are 10 people who are going to post "I disagree" "plausible" or a variation of those either because I said this or because of the context of the message. They are probably reading this and thinking "Haha, I should post that I disagree below because he specifically said not to."
...retards.
