The best thing is to not get into discussions when they are like this because it will go on and on and they will not look in the mirror and see the mess they have made of their lives, and yes, they want your attention be it positive on negative.

If allowed to continue such banter, they are getting their ego kibbles because they know we are finally paying them some attention by responding even if we don't care what we have to say to them or the tone we use.
