This blog seemed to provide a comprehensive list of technique. The following caught my eye of a couple hundred tacks. Live and learn. I am following CoRev’s lead that flamers are not trolls.

Short Term Versus Long Term:
this is a particular case of the Excluded Middle. For example, “We must deal with crime on the streets before improving the schools.” (But why can’t we do some of both?) Similarly, “We should take the scientific research budget and use it to feed starving children.”
Burden Of Proof:
the claim that whatever has not yet been proved false must be true (or vice versa). Essentially the arguer claims that he should win by default if his opponent can’t make a strong enough case.
There may be three problems here. First, the arguer claims priority, but can he back up that claim? Second, he is impatient with ambiguity, and wants a final answer right away. And third, “absence of evidence is not evidence of absence.”
Argument By Question:
asking your opponent a question which does not have a snappy answer. (Or anyway, no snappy answer that the audience has the background to understand.) Your opponent has a choice: he can look weak or he can look long-winded. For example, “How can scientists expect us to believe that anything as complex as a single living cell could have arisen as a result of random natural processes?”
Actually, pretty well any question has this effect to some extent. It usually takes longer to answer a question than ask it.
