Nah the trick is to let them keep changing their arguments, while also subtly changing the entire topic into just shitting on them.
Like say, a bunch of retards join together to autistically screech you're a racist, you keep subtly shitting on them (in a completely neutral way that has no basis on race, at all - as an emergency trump card) until they get the memo that you're shitting on them, then they'll obviously try to outdo you there. This is the part where you start showing their arguments changing over and over again, which usually pisses them off, so they keep trying harder.
Then, just sit back - maybe go on about how hilarious or bad they are, and collect the butthurt.
It probably won't change their faggotry, but it's at least more entertaining than "showing hypocrisy."
