Indeed Pelosi should start pushing legislation concerning this. Not only the rape and incest clauses, but also for reform and bolstering of programs like Planned Parenthood. If the courts want to revisit and reform the legality of abortion, then the legislature should be looking at reforming the programs intended to support mothers of, and unwanted children.
Start with sex education and birth control and run it all the way through setting higher standards for foster care systems in states, particularly those who outlaw abortion, like Texas.
Make these fuckers who are so concerned about those zygotes financially accountable for their well being pre and post natal, up until they are at least 18. Notice I said accountable, not responsible. That means safety nets for those kids to fall back on for physical and mental health. Picture little Marie going to her first day of school in Podunk, Texas, and already she's labeled as the kid of that slut who got raped. Well just move then, right. Have the mom start a new life somewhere else. Way away from family and home. Makes tons of sense. There is definitely a disconnect in how much we care for a fetus and how much we want to shame the fuck out of people, even the innocents.
I maintain that most of those carrying the anti abortion banner are actually more anti-sex. Their sex lives suck (due to a variety of reasons) and unwanted pregnancies are often the result of unprotected sex, so punish those who have sex for any other purpose that procreation.
