I need some advise or perhaps exposure to discussion, because I thought I knew where I stood on a hot-button item.

I need some advise or perhaps exposure to discussion, because I thought I knew where I stood on a hot-button item. I think we are pretty much all against SOPA, right? I signed petitions and sent e-mail and tried to call a few times even.
I understand that many people that I virtually "know" make their living from a variety of things from music and art to writing and photography. We don't want people stealing their stuff, right ?
I sense a contradiction here. Am I just missing something ?
