My grandmother was 16 when she married my 30-year-old grandfather. Not that I would support my child doing so... it's our responsibility to raise our girls to avoid this situation just as strongly as we warn our boys against it.
But, the biological reality of the situation is that we are attracted to one another after pubescence. It is at that time that we are able to procreate, and social rules can only dissuade that so much. Now, beyond that, women are programmed to go after the mate that can best protect and provide. In the majority of cases, that is an older male. Not necessarily substantially older, just... older. It's unusual for women to date down in age, and for good reason. Younger men are not typically better able to provide than their older counterparts. This is not an antiquated perspective; it is a scientific perspective. I would be more concerned about a 23-year-old woman with my 16-year-old son than if the genders were reversed. She wants to procreate. He can't provide yet. He's still under my protection, so that's out, too. That is a substantially more unnatural situation than the reverse, and it is my hypothesis that this is why we see a disproportionate high rate of abuse articles that involve an older woman with a younger male. That's not to say it can't work; only that it usually doesn't.
This guy fucked up. But he doesn't need to be labeled a sex offender or pedophile anymore than my 19-year-old boyfriend when I was 14 does. Ran into him today, incidentally. Still don't feel victimized.
