Yes, thank you.
Growing up without the Catholic dogma and worldview thrust upon you from birth (and consequently playing a part of every action you ever make {unless you lose your faith}, and many thoughts you think) and trying to use the argument that abortion does NOT equal murder is like arguing with an alien. Because from a personal worldview lense, they absolutely do believe abortion = murder with every fiber of their being. It's not enough to just say "no it's not" or make really any argument that leads to that debate. It even affects the views of many ex-catholics who have religious trauma and have been through extensive therapy for it.
No, to you and I, abortion is not murder. But trying to argue that is equal to them arguing to people like us (I assume) that gay people are not just, existing and normal, and not making a conscious decision to be gay. They think it's due to trauma and all gay people are mentally ill and can be cured. However there's no curing necessary. But they'll argue until they're blue in the face that it is. It's the same level of worldview solidification.
You say it causes no harm to society but they'll argue it causes immense harm to God's plan, or whatever. They can also point to the plummeting birth rates which are now almost below the level to maintain the American system. It's a problem that is being debated amongst the highest members of the house and Congress. Of course the reason isn't abortion and is much more complex and societal and due to uncertainty about the environment and wanting to raise children when the parents are a decade a way from buying a house on two full-time incomes now and how much worse it's going to get for their hypothetical children.
My point is you have to see it through their worldview, and understand how they believe it affects them, now only see it through yours.
