Maybe not, but that's exactly what you don't want to do, because you inevitably escalate the debate into a slanging match. None of us want to read posts and threads on this forum where people are having a go at each other. Basically, just don't retaliate, don't be sarcastic and perhaps even just let it go. Plus, it's always a good idea to check whether the other personwere right all along before the slanging match starts.
I'm always right.
