Does " Citizens United " shield me from a lawsuit. [View all]

If I print a list of corporations that I believe contributed to the " Scott Walker Rape Of Democracy ", can I be sued?
If they will not tell us, why shouldn't I be able to guess?

If I am sued for defamation, doesn't that prove that they know that the Koch Brothers (tm) are Evil?

Maybe I could just ask them if they did....

Just wondering if there is a way around this ridiculous Ruling.
