What in "to decide what life you do and do not bring into the world" is not clear?
Someone checks for disabilities with their to-be-born child, learns that they have one and then decides not to abort. This means they conscientiously make the choice to have one.
Yes, and semantics are important. By your definition I make the decision every day not to end the lives of my children, who could for any number if reasons grow up to be a burden on the state.
Calling inaction deciding to do something is just a way to frame things to try and make action the default.

I do not think this need to be debated further.
