I've had the questionalbe pleasure of listening to Limbaugh a bit over the years and having my ear bent by some who think he's infalible.
Last week's Limbaughism is not the first absurd thing he's said, and if you get past some of the language he used last week, it is clear he either knows not how contraception works or he doesn't care, preferring to misrepresent matters of fact to make his point for his listeners.
Al Franken wrote and entire book about this: "Rush Limbaugh is a Big Fat Idiot". In this book he shows over and over again how Rush mistates matters of fact. Rush will say something to the effect of: I'm not making this stuff up, folks, this is all fact. Only it isn't, and he is making it up. When asked about Franken's book, Rush responded by claiming to be an entertainer and having no need to get his fact correct.
Liberals take a lot of heat in recent years from conservatives for simply beling liberal. It is not the liberals who are listening to Rush and his kind: it is conservatives.
It is also conservatives who still pay attention when Cheney, Rumsfeld, et al speak.
I can cite some specifics, such as Rush telling his audience than man is not capable of polluting the planet. Is there a sane man who agrees with that? He's said that having an abortion can leave long lasting emotional scars. That is true, but if one wishes to be honest, one must compare that abortion to the alternatives of giving a baby away for adoption or raising a child you're neither financially or emotionally prepared to raise. He omits those last two.
A lot of us liberals took a lot of heat from conservatives, even family members, when we didn't believe Saddam had any weapons or posed any threat. We were "unpatriotic". We were "atheists" (don't know how that fit in). We were not fit to be Americans if we question our president.
History has proven those of us who did not believe Saddam had the weapons to be correct.
Funny how conservatives change the rules when the president changes. Now it seems perfectly fine to make personal attacks on our president.
Those who listen to Rush, or Hannity, or O'Reilly, or some others of that ilk might re-consider who they choose to listen to.
These people are literally, IMO, poisoning the minds of those who listen to them.
