Can mockery be right?

I read here that it can be correct. What is Catholicism’s view on it?

I think we can challenge another views and ideas, but that we must do it in a spirit of love with a real concern for the person’s salvation. What good is it to win an argument if we drive a person farther away from the truth. We can and should correct error but if we don’t do ir with love we are just “Noisy bells and clanging gongs!”
