Sig220, this is a great subject to take the anti death penalty position on, because logic is on your side...it's also a great subject for trolling because the pro death penalty people know they're right, they just don't know why.
If it were me, and I were to debate the death penalty (and troll the thread), I would point out that anywhere between 200 to 340 prisoners condemned to death have had their convictions overturned thanks to DNA evidence...one could logically assume, since DNA is a relitavely new science, that there's a good possibility we executed innocent men before DNA testing, so throw out this quote-
"Perhaps the bleakest fact of all is that the death penalty is imposed not only in a freakish and discriminatory manner, but also in some cases upon defendants who are actually innocent."
-Justice William J. Brennan, Jr., 1994
This, of course, will get the pro death penalty crowd aroused- and one of them, not knowing the facts, will state they are pro capital punishment because they don't want to feed and clothe a prisoner forever...so you point out that, due to the appeals process, it costs more money to execute someone than it does to warehouse them forever.
A rebuttal from a death penalty advocate, of course, will be that we need less appeals then...(as has actually been done bt the Bush admin., BTW)...Your response will be that with less appeals, we will execute even more innocents...and put a rolls-eyes thingie or a (doh) at the end of your response...I call that the "chum," and it should get a like response from your opponents.
Then, no matter what is said in rebuttal, you wonder aloud if the people in favor of the death penalty feel that way because we execute a disportionate amount of minorities...it's important to ask this rhetorically, but if done correctly you should start getting some angrier responses from the pro crowd...so, once the pro crowd is sufficiently chummed and in a feeding frenzy, you drop your bait-
"Anyone who supports the Death Penalty is no better than those Iranians who tortured that poor man to death." The fact that "poor man" tortured and killed children will have the pro crowd frothing at the mouth, wanting to give YOU 100 lashes and hang YOU from a crane...
So now you sit back, pour yourself a drink and watch the show. Your initial arguments should have attracted allies to your cause, so let them carry the fight- it's only a matter of time before someone alerts Skuzzy to the thread and he comes in with a lock and swinging his ban stick, and the last thing you want is to have Skuzzy reading your posts...but since he rarely investigates problem threads more than two pages back you'll be OK...it's your friends who support you and the enemies who oppose you who'll get in trouble, not you.
If done well you'll have made your point plus trolled effectively, all in the same thread- and, if someone who was on your side got sucked into the debate to the point they got banned, that's a troll orgasm.
Of course I don't troll..not here, anyway...the fish in this stream have seen every kind of bait there is, so no matter how artfully you present it they're still pretty savvy, and the local game warden, Skuzzy, doesn't allow fishing in this stream- And likewise I don't debate the death penalty. I do believe that people 100 years from now will think we're somewhat barbaric for having a death penalty, and I think it's wrong for a civilized society to execute people... but you'll never catch me at San Quentin on the eve of an execution holding a candle in memoriam of some thug who is being executed for maybe three of the dozen murders he committed...
But if I did troll, and I did have more than a casual intrest in the issue, that's how I'd play it.
