Even when I was wandering the wilderness of agnosticism for most of my 20s, I would never have said anything like that. I can't imagine what it's like to have such a corroded soul that the sum of humanity is nothing more than material bits and pieces. That a unique human life is nothing more than some mass of differentiated tissue?
The part that really confirms their demonic nature (well, other than hailing Satan -- which I'm sure they thought was cutting edge and transgressive) is their strident insistence that even late term abortions are fully legal. At that point you can no longer conjure up some comfortably abstract idea of the fetus being merely a clump of unfeeling cells, no when you're a strident proponent of late term abortion it means you are actively advocating crushing the skulls and dismembering babies that would actually live if they were born normally. That is pure, demonic evil and screw walking on eggshells around them and their black sacrament.
Something similar has been happening in NC. The legislature was voting on measures to make abortion illegal for sex selection (what's the point? No one will admit that anyway) and all the bellyachers descended on the capitol with their usual histrionics.
