"4. Promote innovation over litigation. Our efforts should be to protect copyrights and trademarks, not outdated business models."
To me, that is the juiciest nugget in the article. From all appearances, the legislators arguing for SOPA and PIPA don't care too much about our complaints about potential legal abuse and curtailing of the rights of American citizens and companies.
I think stating it instead as a market issue might help, sort of like "SOPA is like something the buggy whip industry would have argued for."
