| Beware of trolls (Photo credit: Wikipedia) |
- Sincere arguers -- they don't agree, but they are polite and point out your mistakes, and when you point out their mistakes they'll concede that you had a point, and you narrow down to where there's not enough data and what is there can be interpreted either way, and call a truce.
- Misguided enthusiasts -- they are sincere about their disagreement, but they're not so polite, and often repeats what other people say without critical thinking, and often they don't react logically as well, esp. when you point out they used fallacies, or red herrings, and some such.
- Scammers -- they know they're lying or using fallacies, but they don't care. When you point out their problems they may turn into trolls, or just leave (in a huff?)
- Trolls -- they're just out to rile you, not to really defend anything
So how do you deal with them? Depends on which type they are.
