I am also aware that Google getting involved is a bad thing.

That's an opinion, one which I (and others) don't agree with.

SOPA is bad for Google, too. Why shouldn't they be involved? The fact of the matter is that corporations are involved in US politics. Like it or dislike it, it's a fact. Advising anti-SOPA corporations to stay out of the fight just feels like a case of misplaced principles. Suggesting that Google sit on the sidelines severely hampers efforts to get the word out and stir up anti-SOPA sentiment among people who may not understand the issue all that well, or may not be particularly interested yet.

I want SOPA to fail. If Google can help with that, I'm all for it, as long as they don't do anything shady or illegal while providing that help.
