I have a big problem believing these numbers.
Simply, I don't think they started with 10^16 foxes and then culled down
the 99% too aggressive or not enough tame.
Given a normal figure of 6 kitten per litter or 10 (very optimistic), it
is difficult to believe that.
A fox couple would need to have 100 kitten, and the female fox would
need to give birth ten times (at least) during her life (improbable, as
the live 1.5 years in the wild and up to twelve - very rarely - in
captivity and I suppose their fecundity after the first two years is
very low).

Now, the article of  1992 give number a bit different from yours:
5% of the males and 20% of the females could breed in in the first
generations.
This is a severe selection, but not as severe as you wrote.
Humans were/are selected under historically a bit less severe conditions.

>From what I remember, it is common, during history, that only 40% of the
males and 80% of the female reproduce.
We can add to this that humans are able to move in other places, if
local conditions are unfriendly. And they are able of assortative
mating. These possibilities can, alone, make up for the difference in
selective pressure.

Again, this is against what the article say.
After any selection, they added new foxes from commercial breed farm.
These foxes were at the early stages of domestication (the point where
the experiment started). So, the chance of interbreeding of recessive
traits is very low (2-7%) for every generation.

Given the wrong premises, I can not agree with the conclusions.

The drifts is, probably, not so big. But I would call it difference, as
drift recall some random process. And this is all but random.

In China, numbers I red said that 10% of the people (usually the poor)
didn't reproduce in normal conditions (peace time). And this is
consistent with the rate in other places like Western Europe.
This rate is a mean, so it is very probable that poorer men didn't
breed, where poorer women had a chance to reproduce with wealthier (than
them) men.
This would have amplified the reproductive fitness of the wealthier men
a bit.

The problem is, if culture is the culprit, it would work everywhere in
the same way. This, in the US is not true, as North-East Asians are law
abiding more than Europeans that are more abiding than Latino Americans
that are more law abiding than blacks.
They are all exposed  to the same culture (or cultures) and the outcome
is very different. And this is consistent.

You only need money.

I don't remember big riots or revolts during the fall of the East block.
The only violence outbreaks were when some groups in power tried to take
the power from another group (Romania was a coup against the Chaucescu -
Gorbachev fell because a coup by the communist party).

Nothing like LA riots or LO after Katrina and likes.

Change in melatonin happened for Vit D deficit, not the reverse.

I don't remember they had any different culture before.
IIRC, when Haiti gained his independence from France, they killed all
the whites in their half of Santo Domingo (male, female and children).
It could not be strange the Dominicans (the other half of the island) as
black as them, but a colony from England, hate and despise them with all
their heart and their past relations (probably even the current) were
very violent.

But Christianity is coming back in Russia because it was resilient or
because the genetics of the russians make it easier to it to return.

In fact, stable societies don't like warrior classes. They want soldier
classes. Warriors' ability to wage a war don't scale where the ability
of soldiers scale much better. And, usually, stable societies are able
to field much more soldiers than unstable ones, for more time and with
stable goals.

In fact, modern and less modern armies usually make a point to kill
their soldiers that don't respect orders and kill out of the
battlefield, without orders and without a good reason.

IMHO, modern armies want soldiers that have an internal "switch" they
(soldiers) are able to turn on and off at will. The "switch" to kill and
use violence.
