I wouldn't be so fast to discount their information if i were you. I don't enjoy their coverage because of its obvious bias, but nor do i watch MSNBC (which most people I know who dislike Fox deny has any bias). Although they do clearly show only information that benefits Republicans, most of the facts are still true. Its good for you to confront arguments of the other side head on instead of avoiding that discussion by calling it a "lie." Joe Wilson had the same problem, instead of giving a speech arguing the nuances of whether or not illegals would be covered by the plan (which there is certainly an argument for), he decided to discredit himself, and his entire party by yelling it as a simple accusation. If you think some fact or figure Fox presents is a lie, look it up for yourself. some of the time you might be surprised at how much of what they say is correct. And when something isn't, confront people you know who agree with Fox about it (AND SHOW CLEAR EVIDENCE!), as opposed to getting in to a yelling match about whether Fox is lying or not. Believe me, its much more effective, and degenerates into yelling matches much less of the time. On ACORN specifically, Fox lied about nothing. look it up. Whether you think what ACORN was offering to do was good, or bad, is a different debate, it happened, and every credible politician acknowledges that. I agree, they did take a definite side by basically covering nothing else for a couple of weeks, but the other news networks did the opposite, by barely even mentioning it. And initially having no real discussions or segments about it.
Add about sub-prime part: people were screaming about that way before even Fox would pay attention. Instead of assuming its wrong, like MSNBC and CNN would tell you, a simple internet search to find out the truth would suffice. Make opinions after that, not now.
