Those are definitionally 'liberal' policies because they 'liberate' corporations from government oversight, rather than a technocratic policy that would place their oversight under government bureaucracy, or a socialized policy that would place their jurisdiction under an element of popular consent.
Even more so, they are historically liberal policies because liberalism is historically and definitionally about privatizing the rights of aristocrats to be bought and sold on the market, rather than outright socializing and creating universal access to them. While some avenues of policy have been socialized, (usually after years and years of legal battles to just make things run smooth) most things in the U.S. are run liberally, by liberals, usually at this point in time either neo-liberals or conservative liberals. Policies like Citizens United are explicitly conservative neo-liberal policies because they increase the freedoms of those with the most access to the market.
Just because you are ignorant of politics and history doesn't mean that we are.
