Illegal political donations by the wealthy is not a dramatic or ridiculous concept. The implication you're making is uncharitable. You're pointing to a conspiracy theory within the realm of reason and asserting that it will surely receive the same quality and quantity of opposition that more absurd-sounding conspiracy theories do. This style of dramatically jumping to conclusions and casting all disagreement as coming from some kind of brainwashed enemy is exactly the attitude that makes many conspiracy theorists look unreasonable.
