Why are we as Americans force fed that all people are equal?

When in reality that's obviously not true

Is it an example of the old saying "A lie repeated enough times eventually becomes the truth"

Here a nothing-of-value degenerate career criminal has the same "rights" as even the best upstanding citizens

And people will actually go to bat for those degenerates because they're "equal"

In some other countries those kinds of people are considered worthless and don't matter

Is it to get us to just passively accept that everyone's "equal" and thus tolerate even the worse of people?

Instead of actually thinking and judging people based on their merits
Smugness intensifies
