Apologies, I meant 'virtue signalling.'

Disparaging others with the intention of trying to show your own value and grandstanding with no intention of actually refuting someone else's argument, isn't debate either.

Examples:

"Goddamned priveleged white males will never understand oppression like us."

or

"Liberalism is a mental disease amongst emotionally unstable snowflakes who can't think clearly like conservatives."

I know many people are above talking like that but it's not uncommon. If someone is willing to talk like that to you because you disagree with them do you really think they're going to take any interest in what you have to say that would contradict their views?
