Its easy for a conservative middle aged, middle classed man to tell a young woman how she should live her life. Now imagine if you were that young woman of 16 or 17 with that decision weighing on you because you made a bad choice.
I'm not sure that's a good example. If that man was the father of that young woman, I'd wager that the reason for any problem is the fact that he did not offer her guidance, counsel, or advice on sex. It's a common problem here, especially with religious families (and more so with fundamentalists); they are uncomfortable discussing sex with their teenaged children, assuming that if they outright forbid it, that will be enough.
Nor would I necessarily trust a 16/17-year-old to handle such a situation well by themselves, seeing as they have very little life experience (something their parents do have, seeing as they have had at least one child). Leaving her to make that decision --and live with the consequences-- all by herself is not ideal, in my opinion. But this is another problem with a clear solution that is nonetheless fraught-- teach sex ed in schools, and ask parents to discuss these issues with their children. Find some way to impress on the most anti-abortion parents to take the lead in helping to reduce the issue by doing something they seem to dread- talking about sex with their children.
Now, if you are comparing a woman in her 20s or 30s with that middle-aged man, your point is much stronger. I wouldn't necessarily dismiss the concerns or thoughts of the man, but I would place the woman's experience far higher when considering the issue.
