If a 20 year old is a child, then why is it perfectly ok with society when they have sex with their same-age peers? Last I checked, children should not be having sex at all. And why do we have 20 year olds in the military? Do we really want children defending our country?

What I also find ironic is how in the older man younger woman scenario, people are insistent on the idea that these 20 year old women are children, but then when we have a situation where a 20 year old commits a serious crime, particularly when it's a male committing a crime against a female, these same people want to see the 20 year old prosecuted to the full extent of the law as an adult and scoff at the idea of showing them leniency because of their immaturity.
