It's even more complicated than that though: "dishonest discussion tactics" suggests that the person is doing it with fully conscious awareness and intent, but this is far from a safe assumption - and, it isn't a simple binary "is or is not", and it isn't only the usual suspects who commit this technique.
Maybe so, but ultimately it's up to us to take responsibility for the techniques we use in argumentation. I would agree that it's not generally a good idea to try to use an attack on the rhetorical techniques someone uses in order to win an argument. It's best to politely find a way to challenge their argument without attacking them personally for the way they put their case.
