I think it’s actually the USA who has an unusually high age of consent. Most of us have an age of consent of 16 and a drinking age of 18.
I don’t exactly think we should raise it, but I sure wouldn’t be against a Romeo and Juliet style amendment. I remember dating an 18 year old when I was 21, and that felt like a big gap. I can’t begin to imagine 16 to 30+. Though that wouldn’t be illegal here either^*.
We have exceptions if the older person is in a position of trust like a teacher, coach etc. Then it’s illegal.
