Paul offers "liberty" for corporations to pollute at will, and offers discrimination against any of the groups mentioned above also (personal liberty to hire whoever you want).
He wants to dismantle the EPA. Do you remember the mighty Cuyuhoga river, and how that river caught on fire because it was so polluted?
Ron Paul wants all abortion outlawed, no freedom of choice for women there.
So I guess there are limits to what is allowable "freedom" in his world. Corporations will have all the freedom they want tho.
