The point is that calling women in politics the c-word is misogynistic, and has a chilling effect on women interested in pursuing public service. Obama has noted exactly that, but, refuses to practise what he preaches when the misogynist is a large donor to his superpac. It begs the question, what other his principles will Obama ignore/bend/violate if the donation is large enough?
Obama, being a politician, lies all the time, abandons his principles, and generally shouldn't be trusted.
I'm not defending Obama nor do I support him. I'm just trying to help you realize the reality that Rush Limbaugh is one of the premier voices of the conservative movement, the Republican Party, etc. wheras Bill Maher has nowhere near the influence or clout that Limbaugh does.
Therefore Limbaugh being misogynistic has a much greater impact on Republicans than Maher being misogynistic does on the Democrats. Just don't want you lot to be surprised when Obama wins women despite Maher calling Palin names.
