Conditional responses to environmental conditions is indeed the key. Under
a lot of conditions, ganging up with the rest of the men in your tribe to
go kill the neighbors is really dumb. The neighbors will fight back and
you aren't going to leave any more offspring after being killed by defenders.
But if ecological conditions are such that you and your children are going
to starve before the next rains come, then fighting it out with the
neighbors *is* a good strategy. Worst that normally happens is all the
males in the tribe get killed. But that's not worst case for their *genes*
since the warriors' female children are likely to be made into extra wives
if they lose and are killed. (Not good of course, but better than losing
all copies of the genes to the tribe starving.)
So what's a really dumb action in some situations becomes a sensible one in

There are two levels going on here. First is the meme level. I have
largely discounted the *specifics* of xenophobic or "absolutist" in this
case. When the ecological conditions are such that you and your family are
going to have a hard time living through the next season then *some* meme
of this class will become common--given enough time, of course.
When the ecology of Easter Island collapsed from severe over exploitation,
the natives sorted themselves out into "long ears" and "short ears" and
went at each other with rocks till 95% of the population was gone. At that
point the environment was able to recover its productivity to some
degree. With improving "income per capita" war memes were quickly
displaced by memes for a peaceful religion (the bird cult) and two or three
generations of warfare ended.
In some ways, what I am talking about here is just specific evolutionary
psychology based reasoning. People have acted as if they understood this
model for a *long* time. As an example, the rebuilding of Europe after WW
II was on purpose because the people in power had the (correct) feeling
that an economically stressed population was fertile ground for nasty
social movements (memes).
What this means is that various classes of memes do better or worse
depending on the conditions of their hosts. So you simply don't have a
consistent environment for memes.
