I hate this quote so much because it is always used out of context as a smear. Often it is twisted to imply something completely different, like you did here. The pronouns are the key to the quote. Speaker Pelosi was criticising the media for being purposefully deceitful.

The point was the negatives were screamed with a megaphone ad nauseam, but nobody talked about the potential good. Therefore "we have to pass the bill so that you can find out what is in it, away from the fog of the controversy."

Some necessary background

> ...the contents of the Affordable Care Act had been publicly available and publicly debated for months when Pelosi made her remarks in March 2010. The bill, in its original form, was passed by the House of Representatives in October 2009, and in the Senate that December. Although the bill was unusually long (the act runs to 906 pages in the legislative record, with many more pages of regulations) its contents had been subjected to intensive debate and scrutiny in both houses of Congress.
