I do not have any particular respect for left-wing liberals with an entitlement mentality who fail to understand basic economics.  I have even less respect for the extremists who think piracy somehow encourages a "new economy" or who pretend wide spread piracy increases sales. These extremists are like young earth creationists, global warming deniers, and others who refuse to acknowledge any facts that contradict their skewed world view.
The bottom line is that piracy is stealing, and that piracy is taking jobs away from thousands of hard working people who make a living making content. I have little respect for the viewpoints of people who either refuse to acknowledge this, or are plain simply so selfish that they think their entitlement to illegal free content is more important than the well-being of hard-working content creators.
Such extremists will oppose any law, no matter how reasonable, that tries to stem the tide of piracy on the Internet that is decimating the music and movie industry.
This in mind, when looking at the SOPA, I have done my utmost to ignore these extremists.
In the early 1990s, the technology was there for really inexpensive digital recording and playback. Because of the meddling of the music industry, that technology was never made available at an affordable level for end-consumers. A digital recorder that should have cost $300 in 1992 actually ended up costing $1200; garage bands had to pay royalties to the major labels every time they bought a DAT to record their own music. 
This was the first of many laws enacted in the 1990s that greatly favored content producers at the expense of everyone else. The DMCA made technical measures to facilitate fair use, such as allowing one to play a game one legally owns the CD to on a netbook, illegal. The Sonny Bono copyright act increased copyright terms to unheard-of levels; because of this act, no works will have their copyright lapse and enter the public domain until 2019.
SOPA is the latest attempt of big content to impose more draconian controls on the Internet. I feel no need to repeat the objections to SOPA posted (PDF file) elsewhere. To summarize: SOPA will give government unprecedented power to suppress speech they find objectionable without due process.
Piracy is a serious problem that needs to be addressed. I do not believe SOPA is the best way to address this problem.
