It's amazing how at some point 'no u' went from being universally acknowledged the most pathetic attempt at an argument and an instant lose to the be all end all of shutting people down and all you have to do is use the magic word 'projection'.

If someone seems irrationally angry at you, for whatever reason, there's a good chance that you aren't actually the problem, just a convenient conduit for whatever pissed them off that day.
