If a parent, man or woman, decides they don't want a child 1 month into it's life citing they're "unwanted" or that raising a child might be "lengthy," would it be acceptable for that man or woman to end the child's life for their own convenience?
Obviously not, and constructing such a ridiculous strawman only weakens your position.

I know this is controversial, but for me the choice stops when you decide that is no longer a bunch of cells with no conscience and becomes a human. At that moment, it passes from being a health decision / convenient decision / means tested decision / psychological health decision to killing a human.
When that potential human being is a human being? Endless arguments have been out there for ages. An embryo for me is not yet a human, just a potential human that has not yet a conscience nor anything like it. After a few weeks, I would hesitate saying that is not a human being.
