Teen brains and other folks' mental instability

"Raising the age to purchase from 18 to 21 to match our rules for handguns just makes sense. Studies show that people 18 to 21 years of age commit a disproportionate number of firearm homicides in the United States. We know from research that the brain does not fully mature until a later age, especially the part of the brain responsible for decision making, risk assessment, and impulse control."

This is from a gun grabber group in Washington State. Pay special attention to that last sentence.

Teens and younger people don't have the same brain as someone older. https://www.urmc.rochester.edu/encyclopedia/content.aspx?ContentTypeID=1&ContentID=3051

The laws of this nation are even set up with this in mind. The US Supreme Court has handed down ruling after ruling using this as the basis. https://deathpenaltyinfo.org/u-s-supreme-court-roper-v-simmons-no-03-633. For instance.

And yet, so many people are screaming, demanding and even reacting with violence to insist teens be treated exactly the same as a mentally competent adult of 25+ years of age. Except of course when it comes to other things.

I'm good with either course.

No, I'm not. Teenagers, as proven by SCIENCE!, do not have the developed brain of an older adult. Treating them as such is flat wrong and flies in the face of the SCIENCE! so many see as their god.

What I am good with is picking a direction. Either SCIENCE! is correct in this - in which case S.T.F.U. about holding teens to the exact same level of accountability across the board - or hold teens to the exact same level of accountability across the board, period.

Trying to have it both ways is cognitive dissonance, not that it will matter to people who are hypocrites on this issue.

Stick to the issue if you wanna debate. Opinions welcome, preferably backed up with SCIENCE! and laws. I've booted people in the past 14 days for personal insults, attacks and ad hominem. I don't like doing it, but I will do it again.
