Although a direct linkage between the murder of their children via abortion and an increased risk of contracting breast cancer by the murderers is good news, it should be remembered that the liberal's response will be predictable...
More money and government protection (from lawsuits) for the murderer's abortionist-accomplices.
Even so, this is a wonderful opportunity for pro-life forces to capitalize on. The key will be to ignore or marginalize any fifth columnists in the pro-life movement who will (as sure as God made little green apples) council that this opportunity not be fully exploited.
I don't expect the government will protect abortionists from lawsuits. Just trying to pass that sort of legislation would attract huge attn to the facts and the risks of abortion. Leftists may regard abortion as their most cherished sacrament, but their high priests are trial lawyers!!
