I think we’re talking about two different things. You’re talking about a little sly wit and a subtle insult. You’re right—that might work.
What I’m talking about is flat-out nastiness and hysteria. Which is what I am seeing here in abundance. I don’t believe that works in swaying the undecideds, or those who are leaning away from your side. NOT UNLESS THE PERSON IS ALREADY LEANING TOWARDS THAT SIDE ANYWAY.
I see what you’re saying, but I think there’s a distinction. For one thing, we’re talking more about ordinary people discussing and debating an issue—not politicians. Mud-slinging does work, and always has. Between the two candidates.
But when debating, style does matter, and when you come off as raging and strident, it does not help. “Strength” does not necessarily equal “crazy, angry and strident” and apparently Bush didn’t cross over that line (I didn’t think he did).
When a whole lot of you come off as splittle-flying and raging, or strident and hysterical, it does not help your case. When you make outrageous claims, demonize people to extremes (“Bush=Hitler” “All Republicans are Mentally Ill”), come on. That’s NOT helping. Especially not when the person you are trying to persuade has been a Republican on some issues, or has relatives who are Republican, and so forth. How do you think that will sway him to your side?
There are two kinds of people you are (I presume) trying to persuade: those who are truly on the fence (rare) and those who are leaning against your side, or are firmly against your side. You don’t need to convince those who are already on your side. They’re sold. You can be barking mad and they’ll probably still be sold.
Those who are leaning against your side are not going to appreciate you demonizing the side that they are leaning towards. If they are reading yours and Sam Stone’s arguments, and they think that Sam Stone makes pretty good sense, the worst thing you can do is tear Sam a new one—calling him a Nazi—because it’s like you’re calling them (those who are leaning towards Sam’s side) a Nazi too.
Now, those who are truly on the fence, well, perhaps calling Sam a Nazi will work. Perhaps. If your argument is otherwise compelling. It’s a coin-toss. And also a risk. Because how many people are truly on the fence?
