The anti religious slurs are coming from people who take their politics as religion, and religion of the worst kind. They protolyze and condemn claiming morally superior grounds. They claim to be the moral majority, but are in fact the hateful extremists. Why they are that way would take textbooks of psychology to explain.
I find it ironic that they are attacking Amy for praising her husband for his support of her career and her having children in addition to a career. However, RBG, was married had CHILDREN during her career and she was a God. They are calling Amy a stepford wife.
RBG SAID: If you have a caring life partner, you help the other person when that person needs it. I had a life partner who thought my work was as important as his, and I think that made all the difference for me.” (The Washington Post, 2014).
