Maybe someone can explain for us what "principles" she is talking about. "Kids" is informal and shouldn't be used when writing, IMHO. "You guys" in in the same category, in my book. Should one be correcting it's use in all circumstances? I don't think so, but I'll assume Mrs. Horvath is just making us think a little about it.
Apparently, she is opposed to the "hippy Cultural Revolution of the 1960s..." Hmmm...
And I'm in favor of it, right? And anybody who ever uses the word "kid" is in favor of it, right? Even somebody who homeschools their "kids" and makes sure that they are educated and
know their catechism is in favor of it, albeit implicitly, right?
Or could it be that the use of "kid" is just accidental today...a cultural thing...certainly not intrinsically evil...therefore not resisted as evil. Maybe there are bigger fish to fry...in the minds of these parents. Did you ever think of that?
