You guys are drawing distinctions at a different location, then complaining that people draw distinctions somewhere else.
Is it or is it not okay to murder a 1-year-old? How about 6 months? How about 2 days after birth? Why? Is it merely the encapsulation of the body inside another body? The transfer of nutrients and blood through the umbilical cord? The one month old is still completely reliant on its mother for survival as it is post-viability, so why do we draw the line at birth?
Because life isn't black and white, and you have to draw lines somewhere.
I'm not religious, so I can't speak for Catholics who are against birth control or condoms, or anybody else with different views. But I believe there is a fairly obvious difference between an IUD, which is a passive measure that must be undertaken before conception, and abortion, which is an active measure taken after the life is created.
Is it perfect? Obviously not. I would much rather a bulletproof method of contraceptives that can be given once via handshake, has 100% effectiveness, prevents the discharge of an egg from the ovary until a reversing drug is taken, and makes my dick bigger during sex.
The primary difference here is I am not acting as though your position is unreasonable or illogical, though your characterization of the opposition is. I simply disagree and have a differing view of the various factors, and the point of this whole thread the Roe ruling rather than the morality, which is clearly one of the most constitutionally unfounded Supreme Court rulings in American history. I do not consider your position absurd, nor do I view you as immoral for holding it, though I do believe the sanctity of life is a moral issue. That's why I disagree with (most) abortion, which is separate from disagreeing with the train-wreck-rulings that are Roe and Casey.
But it is getting tiring hearing a bunch of people act like a biological function, in fact the primary biological function, is somehow a massive imposition on the species. Billions of women living in much harsher times have endured the rigors of childbirth just fine, while the medical risks have been enormously reduced and the non-abortion options to avoid pregnancy have multiplied in both methods and access. It's never, ever been easier to be a woman (or man) of any class. The hysteria over the supposed suffering to be endured by women as a result of the banning of abortion is simply overblown.
If a state bans IUDs I will oppose it, for fuck's sake I'm not even in favor of banning first trimester abortions, but I will not subvert our entire system of governance for this issue. Contested social issues are decided by votes, not judges. IUDs and abortions are not immune from such considerations. If it's a matter of human rights, add it to the constitution; there's a process for that too.
We the people, not we the people who agree with my position and not the other ones.
