Bad faith
About
In a discussion, bad faith refers to the idea of misrepresenting the reasons for one's position, aka intellectual dishonesty. Arguments may be said to be "in bad faith".
Rhetorical Manipulation
Any argument that uses rhetorical manipulation to make its point may be suspected of being in bad faith, although it is not bad faith to use such manipulation to drive home a point which the arguer believes to be true. It may be necessary to look at the pattern of arguments and note whether they are internally consistent in order to make a reasonably good determination of whether an argument is sincere (good faith) or not.
Some rhetorical manipulations, however, work against good epistemic practice (i.e. they are antiepistemic), and therefore may be viewed as "bad faith" by default.
