The government is not prohibiting insurers from doing anything. The idea is to withhold federal funding from abortion practitioners. The insurers can fund whomever they please. The practitioners can still get state funding where allowed, and private funding. So to say that poor women will no longer have access to abortion is factually incorrect.
Congress is not interested controlling the sexual behavior of poor women, they just want to make sure that our federal tax dollars aren't involved in the abortion process.
I hope you're eyes have been opened by the other postings on this thread Milo. Government funding for women's clinics has been cut already and they pushing for more - for ALL their services - that includes family planning IOW birth control.
Since anti-choice groups are pushing for this legislation, it's obvious it's just another ploy to destroy a woman's right to her own choice. They couldn't get Roe vs. Wade repealed, so they're making it all but impossible for women to exercise their right to an abortion if she so chooses.
This destruction of rights by the back door is insidious and infuriating.
I daresay certain conservative groups are now doing the same thing with voting rights for minorities. If you find the technique abhorrent for one group, you should find it abhorrent for EVERY group whose rights it threatens.
