That is an excellent response. I forgot to mention that another thing I will say is along the lines of, “Yeah, you just keep beatin’ that race horse. Beat it like a rented mule. Beat it until it means absolutely nothing anymore.” Then move past it.
Point out the lack of jobs. The majority of Libs who spend all day posting online are there because they can't find work. Beat that drum repeatedly. Point out how useless their Master's degree is in Obama's economy. Say something like, "Wow, it must really suck to have spent all that time, money and effort in school to just have it all wasted in Obama's Economy." Use "Obama's Economy" like you use "Obama's Afghanistan." Illustrate Obama's lie of "no more than 8% unemployment" with a chart from ShadowStats.com that shows the true unemployment to be around 22-23%. An unemployed Liberal is fair game. Humiliate them. Don't use this tactic on anyone but a true, black-hearted Lib because that would just be mean... not to mention possibly karma-inducing. Especially in Obama's Economy. Any one of us could be next.
