It is clear that the Republicans are going the use the tax angle as their new main attack against the ACA. This framing needs to be countered as soon as possible and in such a way as to force opponents to explain.
Our political and media supporters are much to polite to use such blunt and divisive language. So it becomes incumbent on us to shift the frame. So please refer to the enforcement provision as the Slacker Tax as often and consistently as possible.
It worked very well with the "Death Tax" (everybody dies after all). You are not a Slacker so you aren't taxed. After all shame is the enforcement mechanism in the law it is only our patriotic duty to help out here after all.
