Not to mention it's awfully presumptive to apply it to people facing the issue. I.e., invariably its those who are pro-rights who are told to understand the other side; why? If you can't get pregnant, your opinion on abortion -necessarily- is secondary to those who can, and it's they who need to seek to understand (and, I would argue, that in the same way that "wisdom is knowing you know nothing", sufficient understanding means realizing you can't fully understand because it doesn't directly effect you; that doesn't mean you can't have an opinion, but it does mean you shouldn't be trying to enforce it upon those actually effected by it).
