Everyone had a past both as oppressor and oppressed. No race is
inherently good or bad.

The pathological vilification of "White people" and "White racism"
as the root of all evil has very little to do with history.  It
has very much to do with resentment, racial hatreds and a propagandizing
educational system which educates no one.

The extremely vicious and brutal slavery practiced by Asian
empires, African empires and Muslim empires is scrubbed from the
curriculum.

The enslavement of millions of European and Slavic people is never
mentioned.  Particularly not when their enslavement was commited
by "nonWhite" people.

The repeated invasions of Europe and European territory by Muslims are
not mentioned.

The genocide across the Middle East of non-Arabs by expansionist
Islam is not mentioned.

The destruction of the last outpost of the Roman empire--the
Byzantine empire, its eastern half--by the Turkish Ottomans, anda
the Turks' wholesale appropriation, outright theft, of their art,
knowledge and culture is not mentioned.

Not to mention how many of the Moorish culture we are told to admire
was cribbed wholesale from Romans, Hellenes, Persians.

Millions of Indians were slaughtered by invading Mughals.

Bantu blacks in South Africa have no legitimate claim to any south
african land.  None.  They are invaders from the north who attacked
the small tribes of indigenous peoples living there, after White
pioneers had settled the vacant lands of the Cape.

And so forth.
