when encountering an argumentative twit
When encountering an argumentative twit online or in person, this method is reliably effective.
If talking in a friendly way, just sharing my two cents, and some hater or troll or twit jumps all over my comment to disagree with it, I ignore whatever they said, and reply with deep sincerity and without the slightest hint of sarcasm, "I am so sorry that I offended you". They invariably look aghast and proceed to insist that I did not offend them in the least, moreover, I couldn't possibly offend them if I tried.
To which I reply, "Oh I'm so relieved. For a moment I thought I had upset you", to which they reply somewhat hysterically, "You didn't upset me! I'm totally fine!" To which I reply, "Are you sure? Because you sound upset. I think I really did offend you with my words". And so on.
People don't like to admit that you have the power to upset them, to offend them, or to hurt their feelings. They back off. If this conversation is happening in person, I put my hand on my heart and gaze at them with genuine concern while I express my deep and profound apology for having so much power over their feelings.
