Because they recognize that abortion is not Constitutional and that Brett Kavanaugh is a strict constitutionalist, they want to stop his confirmation at any cost.
It is not just about abortion, though. Liberal women are conditioned to think of abortion as the be-all and end-all of rights, to cause them to be complacent when all other rights are dissolved by leftist activist courts.
“It is not just about abortion, though.”
Damned straight it isn’t! The RATs know that their days of using the SCOTUS as an unelected legislature are over with Kavanaugh’s seating. Everyone talks about Ginsberg being the one they will fight and die on. Nonsense, with Kavanagh, the Court is changed and Ginsberg doesn’t really matter in the short term. My biggest worry right now is the Republicans in the Senate.
Idolatry, regarding sexual sins and child sacrifice was primarily the reason God abandoned the Children of Israel, his very chosen ones and allowed other nations to invade and enslave them. That same story is playing out concerning the idolatry of sex in all it's various forms in the world today which includes the religion and idolatry of abortion which is nothing but child sacrifice to the God of sex. The only thing we lack in the US are male and female prostitutes quartered in our places of worship, but maybe not, when we consider the problems in the Catholic church. If something does not stop the current rot in our controlling institutions, another nation will soon be able to take this one over and it will not kowtow to the schemes of the American left and it's idolatrous culture.
The left’s obsession with abortion goes even deeper than that.
Their ultimate goal is the destruction of morality based western society.
A society that murders thousands of unborn babies a year cannot also maintain the facade of being morality based. Once the facade crumbles, the society will as well.
