Isn't submitting a response enough to convince the rest of us plebs that you agree or have other strong feelings about the parent comment?

Chances are good that, unless you're James Joyce, folks will read through the entirety of your statement to draw inflection from what you've conveyed.

When you don't agree with the parent comment, have you kicked things off with, "Not this" or, more succinctly, "!This" before making your counterpoint?

I understand “This” below a comment as a sort of a sign that it messages exactly what the replying person wanted to say. Akin to inheritance. If you just reply with an extension, it may not be as clear that you fully support it.

have you never heard or read someone start a reply with “i agree” or “i disagree”? in any case, what an awfully off-topic, pedantic thing to get bent out of shape about.
