Do you believe young women (or men) who are 21, 22, 23 or 24 should be allowed to consent to relationships with older men or women who are 10 or 20 years older? I know we should have free will, but should we be allowed to self-destruct just because we “can”?
The age of majority is a pretty arbitrary line that we draw; I don’t see how this would be fundamentally different. We already “encroach” on interpersonal relationships by not allowing adults to date minors (which again is defined completely arbitrarily).
