Cute. real cute.
Not too intelligent, but cute.
You have a better idea than to point out what really should be done rather than banning the Confederate battle flag, then do it. I say countering with a slogan to ban the Demorat Party evokes the history of that Party.
If you have a better idea on how to address Demorats that try to hang that flag and its perception of slavery/segregation/racism on Republicans - bring it to the table. Otherwise, I suggest you keep your liberal remarks to yourself.
Whatever the agenda/premise/argument/etc., is, it needs to be addressed - we cannot ignore it as you have. Until we control the agenda/premise/argument/etc., we are stuck fighting on their terms. You have a better idea, instead of your quips to join the Demorats?
