Putting it into another context, which I realize is not really along the same lines, should we ban all alcohol from being served in any establishment that happens to have a parking lot? The answer is, of course, no. Should people exercise good judgement before they get into their car to drive away from that establishment where they, perhaps, have just consumed too much alcohol? Yes.
At the end of the day, whether or not abortion is legal or not is not the problem. Whether or not a business serves alcohol to potential drivers is not the problem. It all boils down to judgement. There is good judgement, and poor judgement, and I think it is far more valuable, and far more important to find ways to help people along in making good, sound judgement before alternative decisions must be weighed in on, than mandating whether a decision can be made at all. I want to live in a world where sure, we all have many options before us, but wherein the majority of us are apt, capable, and compelled to take the right path all on our own.
