As usual, you can read the words - but fail to discern the message.
The sentiments espoused by the woke anti-racists are ignorant. Ignorant of truth, ignorant of facts, ignorant of history - take your pick, it's usually more than one.
Let's take an institution recently deemed "racist" by the woke: the nuclear family. The practice, which predates recorded history, has been the foundation of the current levels of civilization we enjoy today. It's fostered the creativity in the inventors of the world to create technological wonders and solve global problems.
In the communities where it's deemed racist, the practice has been subverted by 40 years of government programs that give incentives to women to remain single and raise children in fatherless homes. Crime in these communities has risen steadily throughout that period.
Now, rather than fix the problem (destruction of the nuclear family), the stated goal is to destroy the nuclear family within other communities - because their refusal to destroy themselves is racist. Rather than build themselves up - the stated goal is to tear others down.
That, my friend, is a simple example of what Prager was talking about. Fighting to destroy the nuclear family is fighting the values that the country was founded on.
