Why assume I am being disingenuous?
It's not an assumption, it's my perception, and it's based on years and years and years of experience with people in f2f and online disagreements. It is a style of argument, and you are far from the only practitioner of it.
I don't necessarily doubt that you do sincerely believe that "you catch more flies with honey than with vinegar," but even taking that at face value: it's not like you're going to change anyone by nagging them into it. Quite frankly, your approach often pisses people off, provoking the exact response you decry.
Funny how that works, huh?
