Actually, the jerkass does not have a point at all. Besides the fact that comparing the appointment of certain officials with a simple majority instead of a supermajority to rape is ridiculous, his analogy is mathematically illiterate and logically ridiculous.
“Forget the Senate for a minute,” he said on his radio show. “Let’s say, let’s take ten people in a room and they’re a group. And the room is made up of six men and four women. Right? The group has a rule that the men cannot rape the women. The group also has a rule that says any rule that will be changed must require six votes of the 10 to change the rule.”
So in other words, the group requires the lowest possible majority to change the rule. IE, exactly the same as what Reid changed the rules to be. Rush actually does not understand what a majority is.
Limbaugh continued his analogy by saying that “every now and then some lunatic in the group proposes to change the rule to allow women to be raped. But they never were able to get six votes for it. There were always the four women voting against it and there was, you know, two guys.”
Ok, so six would always vote against and four would always vote for. Ok.
“Well, the guy that kept proposing that women be raped finally got tired of it,” Limbaugh told his listeners. “He was in the majority and he said, you know what, we’re going to change the rule. Now all we need is five. And the women said, ‘you can’t do that.’ ‘Yes we are, we’re the majority, we’re changing the rule.’ And then they vote. Can the women be raped?”
This is the really WTF part. No, the man is not in the majority - only four people out of the ten in the group are pro-rape, so he would not be able to pass this policy. And wouldn't he need 6 people to change the rule anyway?
Leaving aside how the man would even pass this rule, this would not lead to the consequence Rush thinks it does. 5 men could vote to legalize rape, then 4 women plus one man (let's assume he made a mistake earlier about how many men are anti-rape because he can't count) would then vote to make it illegal again. Same if the rule is changed to 3 people only. The women could also just vote to change it back up to 6 or 7 or whatever.
To be honest his use of this analogy leads me to seriously question whether he has any idea how the Senate works at all. Or even if he understands how numbers work at all.
e: Even if we're charitable and we adjust the numbers so they actually make sense his point is still dumb. What it's really arguing for is a need to have human rights in place to protect minorities, not setting the bar a little higher so that it's a little harder to outvote some minorities.
