The title refers to Grade School arithmetic fractions, which was replaced by Elementary School mathematics. Early political correctness? Then, there was, 'The New Math.' Where did THAT ever go? Currently, I hear of another style, giving the youngsters a bit of difficulty.
There's been a problem teaching, because kiddies can't grasp everything as quickly as others, in a given, prescribed time.
Don't get me started on book censoring/revising/outlawing by those who all of a sudden, "know better." To that, add statue removal, re-naming of buildings and schools. It all amounts to revising and eventually erasing history. Please read, "1984," before that too is criminalized by those, ahem, who know better. History, after all, is what we utilized in making a better world for our children. We got better because we recognized and improved upon the mistakes of our predecessors!
Today's world gave birth to left, right, liberal, woke, fake, self-aggrandizement, hubris, insurrection, cancel culture, LGBTQ+., CRT, constitutional defiance, Lite/Light everything, Global warming denial, racist revival, E-vehicles, drugs, looting, suicide bombings, nations overtaking more territory when they can't manage their own and so, so much more!
Political parties refuse to pass measures merely because they are submitted by the other. Lobbying is actually legalized bribery, accepted, even encouraged by more than a few.
Unless unified, concerted efforts are enacted, this tiny dot in the solar system will become just another lifeless asteroid.
Remember meetings in Civics class? That's where disparaging viewpoints are discussed and agreements are met, then enacted!
Why is that so difficult? I'm sorry. I forgot mega-egos are involved, along with hubris and the puerile. Look it up. That's called, "learning."
So, what is the Lowest Common Denominator? Based on all the above plus others, we've allowed the following mantra:
"You have the right to say, do and be whatever you please, as long as I approve."
