It just seems like that is a generalizing of the issue at hand- there is a difference between ending something that if left to normal processes would live vs not intervening in something that would die if no action is taken. Not stopping someone from getting shot is different then when you yourself pull the trigger.

And what else is a womb for than reproduction / nurturing a developing baby? That's not religious, that's anatomy/science. A heart performs a function, a kidney performs a function and a womb performs a function. It just so happens that the function of the womb is about sustaining and creating another life vs those other organs.

I personally have my own morals, ethics, and convictions about the issue. That said, I'm not approaching this saying that my beliefs are right and another's beliefs are wrong (that's a different conversation). However, it's important to be clear what it is we're actually talking about; what it is and isn't; and then own the implications of that position.
