We haven't covered a Limbaugh rant here in a long time, mostly because Limbaugh himself has become irrelevant, but this is one for the ages because it demonstrates that sexual consent is not a difficult concept to understand, even for right wing nuts.
Limbaugh and his ilk understand what it means to consent, they just think it's bullshit.
via Media Matters:
LIMBAUGH: "You know what the magic word, the only thing that matters in American sexual mores today is? One thing. You can do anything, the left will promote and understand and tolerate anything, as long as there is one element. Do you know what it is? Consent. If there is consent on both or all three or all four, however many are involved in the sex act, it's perfectly fine. Whatever it is. But if the left ever senses and smells that there's no consent in part of the equation then here come the rape police. But consent is the magic key to the left."
It's clear Limbaugh thinks this is a clever shot at the left, but he's absolutely correct that consent is the key to any sexual encounter of any description. Moreover, it's key that the person who consents is actually capable of consenting. Someone who is impaired for whatever reason cannot consent.
They understand what consent means, they just don't think it should be required. Trump's Republican party is effectively pro-rape.
