Do you think - from a white man's perspective - that the continued decrease in % of US population that is white is something that should concern them?
Yes, but not because they have a shrinking percentage, per se.
The concern should be for their decrease in both fertility and chosen reproduction. Fewer of them
can have children easily and fewer of them are
trying to have kids, at all.
Those are both sources of concern for me as is the sharp increase in suicides among certain sub-populations within the so-called white population of the U.S.
How about the increase in % that do not speak English?
Yes, but again not for the reason that you might be upset.
I worry about the quality of our schools and our teaching. I worry about it in the areas in which English is still largely the only language spoken, as surely as those with a major second language.
