One objection to changing the system so that it allows teens to love adults is that the brain doesn't fully develop until they're 18 or even 25. However, we know Blacks have lower IQs and it would be immoral to prevent them from voting because of their IQ. That would be racism. Just because someone has a poorer brain, such as teens, blacks, and disabled folk, that doesn't mean they should be barred from activities. To be clear, I do think ageism that bars teen marriage may be similar to racism and ableism.
