Don't worry, they won't get approved. Lot's of folks today have sent protest letters to congress and some of them have already backed out.
These parasites that run our legislative don't do much research on what they are signing. It's a mob mentality. Since nobody was complaining they were going ahead with this stupid law (great idea having the US government messing with DNS tables). Now that their voters are rebelling against them, most will back down. The only ones left will be ones paid directly by the media lobbies.
And IF for some miracle they eventually pass this (which I doubt they will), all we need to do is to get the IP address of the dealers' sites and add to our personal routing tables. No biggie.
