The way kids are today (and their behavior proves them still “kids”, not adults), perhaps we should move it BACK to 21. (Let’s recall it WAS higher, please - funny, in days when men behaved like men at the age of 15.)
After all, if you’re all for “rights”, then you should not object to there being no age limit on voting. Why not go all the way? Any child that can and wants to vote should be allowed to.
Good point about the security. Then let’s add security at the entrances to their campi. Most do have campus police, though.
And as so many are wont to ignore, please note I do think other adults working on campus should be allowed. I know, probably not good enough, but then, why is just security personnel at defense plants and so on good enough?
