I have heard people opine that elective abortion should be permitted up until birth (38 weeks plus). That is one "hard line" I personally find indefensible.
It's also not uncommon for a fertilized ovum to fail to implant, so banning it any time after "conception" is the other "hard line". And some kinds of birth control allow conception without implantation. Trying to ban birth control is another very hard line.
And of course some very religious people think abortion should be basically on demand, and some agmostics think it shouldn't, it's not a pure correlation.
But that issue is of course most closely aligned with religious beliefs. Not much else really is these days, maybe capital punishment and a few other things. "Taxing the rich", or not, isn't a religious thing, giving aid to Ukraine isn't either, giving it to Israel often is highly so.
