Utter nonsense. They just don't want to have to pay for your birth control. There is a huge difference between banning something and saying, you can get it if you want just don't make me pay for it. And Catholics are not all republicans. That's silliness.
Interestingly most protestants have no problems with birth control, like a condom or "the pill"... While most have some problem with abortion they certainly aren't against you getting birth control, they are simply against forcing people with religious objections to purchase and provide (thus forcing them to "sin") abortive agents or, in some few cases like the Catholic Church, birth control for others.
I agree, read the thread!
