On one hand, most Americans are hypocrites on the age of consent (if they are Christain).
Christain Americans: 13 YEAR OLDS CAN'T CONSENT!!
Me: Don't you worship a God that had sex with a 13 year old girl (Mary)? I mean, pedophilia or atheism, you decide bud.
But also if young people are allowed to legally consent to sex (Korea was the first person I met that defended pedophillia, so it's a new view to me and I kinda have to play Devils Advocate because when virtually everybody agrees with you, you don't come up with as good of arguments as someone that is in the ideological minority because the ideological minority thinks about the majority's positions way more than the other way around). A flat earther can make better arguments justifying a flat earth than a random person that thinks the earth is spherical because the flat earther thought about their position way more. I believe the earth is spherical, but I don't think I could win a debate with a flat earther on the earth's shape because they've thought their position on this issue through much more than I could. The same thing would apply for pro pedophilia people vs your typical anti pedophilia person.
Korea's argument: Children can consent.
Me response: What about drunk people? Can they consent?
His response: No; drunk people might regret the sex they have.
I don't think this is a good response. If sober adults consent to have sex and enjoy it the full time, but the woman regrets it an hour later (lets say she was a virgin and her hymen broke, so she regrets it an hour later), the man is not a rapist. If the woman gets an unintended pregnancy, she regrets that sex. But if a drunk person regrets sex 5 hours later, it's viewed as rape done by the sober party. So I don't think the fear of sexual regret is a good enough reason to charge someone with rape.
So either drunk people can consent (not Korea's position if I understand it correctly) or children can't consent (not Korea's position if I understand it correctly), or there is some other reason why drunk people can't consent but children can with Korea's logic.
