Both of you are wrong and severely autistic.
First for you, stop trying to deconstruct the age of consent. Yes you are technically correct that at 17.9 yrs and 18.1 it's same shit. But we have laws and the laws necessitate that we draw the boundary somewhere, even when it's somewhat arbitrary. Keep in mind that you have used this deconstruction in the same way that shitlibs use it to deconstruct racial categories, "how do you know who is white". Not good.
As for Raptor, we've had this discussion before, and it's nearly impossible to conduct, cause she will accuse everyone of pedophilia and grooming rather randomly.
- US is not the only one country on the planet; countries in the EU often have 16 or even lower as the age of consent
- it's obvious that adolescents can consent at 16 (and younger) simply by taking notice of the crazy amounts of sex going on ad that age.
So the problem here is adults trying to mess with adolescents, or worse. If you're a dad and you have a 15 yrs old daughter, you don't want her to fuck 25 old males, even if she wants to. But to argue that she cannot say yes to her 17 yrs old boyfriend is patently ridiculous. There's a reason sex ed is targeted so much at these ages, 13-14-15.
So we need rules and laws based on a pragmatic attempt to keep adults from corrupting adolescents and children, which is rather easy due to power and wealth imbalance. Parents have an interest to protect their offspring too. At the same time, people should start arguing that 18 is some sacred age where you are suddenly able to consent, as if the Amerimuttlands are the only country on the planet and everyone else is wrong and degenerate. We all know the truth is kinda the opposite.
