See, your problem is you don't see the difference. Rush was a very highly paid racist blowhard, paid by billionaires and whose programs were distributed for free to radio stations, while he made hundreds of millions. Moore made relevant independent documentaries about pressing social problems and injustice, he made a few million dollars doing it too, but not too much money by today's standards and I understand he gives some of it away and supports social causes.
Moore is a caring conscientious human being, Limbaugh was on the psychopathy spectrum, a fellow travel with the traitor Trump. Support a traitor and you become one yourself.
