But why do all that digging when a shovel is perfect for smiteing the fools?
Actually very few of us have the resources so our best chance is to use the fact checkers. No matter which one you use someone will say they are bias but what difference do the naysayers make, if two or three fact checkers you're comfortable with agree on a point, you can feel confident making that point. That's the best you can do, chances are you're not changing the other guys mind, you're just making yourself comfortable with yours.
