Being pro-abortion does not mean you are pro-women.
Abortion was championed in the '60s by perverted misogynistic males in the Sexual Revolution who wanted to have sex without any consequences.
What's my evidence? Andrea Dworkin was a super feminist in the '60s. She wrote:
"In the garden of earthly delights known as the sixties counterculture, pregnancy did intrude, almost always rudely; and even then and there it was one of the real obstacles to female f** on male demand… it even led women to say no.
Throughout the sixties, the birth control pill was not easy to get, and nothing else was sure…Fear of pregnancy provided a reason for saying no: not just an excuse but a concrete reason not easily seduced or persuaded away, even by the most astute or dazzling argument in behalf of sexual freedom. Especially difficult to sway were the women who had had illegal abortions already. Whatever they thought of ucking, however they experienced it, however much they loved or tolerated it, they knew that for them it had consequences in blood and pain and they knew that it cost the men nothing, except sometimes money… Pregnancy, the fact of it, was antiaphrodisiacal. Pregnancy, the burden of it, made it harder for the flower boys to uck the flower girls, who did not want to have to claw out their own insides or pay someone else to do it; they also did not want to die.
It was the brake that pregnancy put on ucking that made abortion a high-priority political issue for men in the 1960s—not only for young men, but also for the older leftist men who were skimming sex off the top of the counterculture and even for more traditional men who dipped into the pool of hippie girls now and then. The decriminalization of abortion—for that was the political goal—was seen as the final fillip: it would make women absolutely accessible, absolutely "free." The sexual revolution, in order to work, required that abortion be available to women on demand. If it were not, ucking would not be available to men on demand. Getting laid was at stake. Not just getting laid, but getting laid the way great numbers of boys and men had always wanted—lots of girls who wanted it all the time outside marriage, free, giving it away. The male-dominated Left agitated for and fought for and argued for and even organized for and even provided political and economic resources for abortion rights for women. The left was militant on the issue.”
