I think this kinda thing is why you received the response that you did, Biff. You're basically throwing up your hands and screaming "somebody do something !" while telling the people who are explaining to you why your perspective is a bit off base that they're idiots.
You don't have a solution, which is fine. I don't either, which is also fine. That doesn't mean that cops in uniform or national guard in uniform need to be teaching kids. If you listened to the content of what posters are saying to you, then you'll hear that there are a few issues.
First, teaching is hard.
Second, teaching is underappreciated.
Third, the idea that you can replace teachers with random public servants is pretty insulting considering points one and two. You're basically insinuating that it's teachers' jobs to babysit your kids. I don't know your politics exactly, but teachers' job descriptions are among the most contested issues historically and the trend has been to massively expand job responsibility while denying teachers security and pay. (I'm a third generation teacher, so I've been hearing these stories my whole life, so it's not really even that unique to the COVID-induced calamity that we have).
Four, it's fine to have cops, etc. babysit kids, but that's not the primary function of education, so while the kids will get some socialization, they won't get educated. Likewise, cops, etc. can babysit kids, but being in uniform with a badge and a gun seems to undercut the very real reality that a lot of kids, particularly kids from working class backgrounds and non-white kids, have super complicated relationships to law enforcement. I realize that's inconvenient to the narrative, but if the goal is to make sure that kids are well taken care of and educated, then the entire charade feels like cheap copaganda.
