If sex without consent is rape, and minors can't meaningfully consent to having sex with an adult, then having sex with a minor is kinda rape.

His comment about 17 vs. 18 years old shows that he's detached from reality. The law has to draw the line somewhere, it's necessarily arbitrary to some extent. It's still okay to discuss such nuances, but then don't be snarky. Context matters too. What point was he trying to make here and why?
