ELI5: What does it mean to argue in bad faith?
gpt
It means that you're not arguing to come to a mutual understanding. In a true debate/argument, both sides must be willing to acknowledge if the other side has good points and be open to changing their minds. If you tell someone you want a "debate" but you really just want to antagonize them or preach to them, you are lying when you say you want to "argue".

Bad faith generally is an intent to deceive.
