After four years of waiting, finally heard someone applying the transitive property of mathematics to the Supreme Court's Citizens United decision wherein it is declared that Money = Speech. (Maybe someone somewhere did it earlier, not the point.)
Seems very straightforward that if Money is Speech then anything purchased with Money becomes Speech also. Anything. At all. For example:
Money equals Speech. Bullets are bought with money. Therefore Bullets are also Speech. Speech that communicates by the rapid transfer of kinetic energy, but Speech none the less.
Law professor tells senators: If money is speech, outlawing prostitution is unconstitutional.
