It would be a strange use of sarcasm, in my opinion, to use it to keep people arguing to no avail. I'd rather call that disingenuous goading, not honest sarcasm

It would be a strange use of sarcasm, in my opinion, to use it to keep people arguing to no avail. I'd rather call that disingenuous goading, not honest sarcasm. Personally, I'm rather fond of sarcasm and irony. But if I find myself in a dialogue, and another party seems to not get the point of a sarcastic or ironic comment, then I will point out the miscommunication.
