Those that argue in bad faith usually abandon consistency in the process. Because they don’t believe in the argument they are presenting, as soon as they are proven wrong they simply pivot to a new, and likely, contradictory argument. This often occurs because their real reason for their desired outcome is abhorrent (and they are aware of that) but they argue a different reason that would have the same outcome. This is prime red meat for racists and misogynists, as an example.
