One, please stop sharing Rick Lax's videos on social media. They are by far the worst, and dumbest "tricks" on the interwebs.
There is so much better, and more interesting content out there.
Two, I am still in favor of dropping the voting age to 16. And I believe, if there is a minimum, there should be a maximum. Say, once you hit 70, you can no longer vote. Same reasons. There's nothing saying you're responsible enough at the point to truly understand what you're voting for, and furthermore, you're no longer deciding YOUR future. You're almost done here. Seems morbid, but it's a fact of life. Let the younger people choose the future in front of them.
I know, I've suggested that before, and people whine, "You can't do that! That's age discrimination!" Really? More so than saying a 16-year old is incapable of understanding issues, and how they impact the world, the nation, and their own lives? You're making a judgment on all young people, and thereby preventing them from voting based on an assumed ability, or capacity to handle that process, but not on older people who might actually have failing faculties? And yes, I know many very sharp, keen 70 year olds, but I also know some I wouldn't trust with the TV remote, so why is OK to blanket one age group negatively, and not another?
