I don't think panic should really be a course of action, even if these bills do get passed. We couldn't affect them even if we wanted to, given that we can't really organize enough people in time for something like this, and even if we could, they would still hold the ability to vote any which way they choose.
It's best to follow this with an emotional detachment. Whatever happens with the house and senate and politics, will happen. The Koreans, from what I understand, have a cultural concept of Han, which is, to quote wikipedia, "feeling of unresolved resentment against injustices suffered, a sense of helplessness because of the overwhelming odds against one, a feeling of acute pain in one's guts and bowels, making the whole body writhe and squirm, and an obstinate urge to take revenge and to right the wrong--all these combined.""
I don't agree with a lot of it, but I do agree with one thing. Come the next electoral cycle, every American who doesn't like what happened has an opportunity before them. They'll know who did or did not vote for these bills. And they'll be allowed the opportunity to see them out of a job, and out of politics, come the next election.
Assuming they actually take that oppurtunity to do so. And don't just blow it off to do some family bonding or have fun. In all honesty, I can't fault people for wanting to enjoy themselves with the free-time offered to them, instead of opting for vote spitefully.
