Historical trauma is not a new topic in this forum.
Many threads, of different ages, exists with discussions of historical trauma.
Not a few such threads are a mixture of combativeness with posts that are thoughtful and compassionate.
Rather than revive old ones, perhaps there is value in a fresh thread on the familiar topic.

It is easy to let the emotions override common sense
when considering man's inhumanity to fellow man.
It is convenient to vent in posts at forums like this,
such posts may make the poster feel something of value
but at the expense of giving offense to others.

Regardless, at the same time,
generations of caregivers and members of the helping profession
confront, and are confronted with,
the consequences of historical trauma, in those who need healing.
And that struggle to heal and to overcome continues,
regardless of all the noise and venting that goes on.

Here is a link to one example.
Addressing the Contagion of Violence

Might examples like the preceding,
provide a constructive alternative
to the ranting and name-calling posts
which vent emotions while giving offense?
