part of the conservative ideology is that children are property and should be molested, not heard.

When I was a kid, my mom was outraged that somebody made the statement, "children aren't their parent's property."
So, yeah

In ancent rome there was a law,that went something like "you cannot sell your son into slavery a third time". Americans would see that as a violation of parental rights

Of course! Especially those from the party that wants crops to be picked, but doesn't want anyone who would actually do it to exist or survive in our country. And because the term "child labor" in general is unpalatable to most people. For good reason...

Currently every politician making a name for themselves will frame anything they can in any way they can. Words have little meaning lately so you just say whatever the fuck you want and worry about the angle later.
