A question for you: In that case, should the age of consent be raised to twenty-five? Should the voting age be raised to twenty-five? Should you not be permitted to get a mortgate, etc, until then?

People are either considered adults at eighteen, or they aren't considered adults at eighteen. I don't think you can legislate for brain development in one's early twenties, unless of course you are in favour of making twenty-five or thereabouts age at which one is officially an adult.

Personally, I ask two questions: 1) Are these people over the age of consent? 2) Are they consenting? Anything else is none of my business.

Here's a good article on the subject: https://medium.com/lucid-nightmare/im-calling-time-on-the-bashing-of-age-gap-relationships-22e09ae93b1a
