you've decided that life begins at conception and from that viewpoint have attached all of the positive attributes and qualities of a healthy happy cognizant child to it with no regard to individual circumstances. From there you can only impose the ideology that choosing to not have a child after conception is equivalent to murdering an actual child. I disagree here, and again we cannot ever agree - your ideology doesn't allow you to consider any other view.
I firmly believe that the decision to no have a child is an important and difficult choice that needs to be left to the person or persons who would be impacted in the light of their own individual situation, and that this allows the best possible outcomes for everyone involved. I would add to this argument, but any detail I put will get called out in an individual quote to be rebutted so I'll try to just stick to the general point rather than get into details for you to stumble over.
