Society is in general revolt over the current copyright law terms. The man in the street realizes the media giants have gone too far, but some how congress can't see it yet. Maybe they are just starting to see there is a problem.
In my experience it is completely mixed. A lot of people think that it is the law, so it must be good. The techs where I work first heard about SOPA when I went to a wikipedia page in front of them during the blackout (not deliberately, actually was trying to look something up); they didn't much care, and since I knew about it I believe they thought I used the internet too much. The close relatives I have mentioned it to (once) didn't know what it is either, probably because they are informed by TV news and newspapers, which never mentioned it at all, at least before the blackout. It is not something I would particularly want to talk about face to face, simply because it is not 'cool', and that matters.
Maybe your experience is different.
