That isn't even true in the abstract, and as a widowed mother who raised an exemplary child from infancy to staunch conservative young adult, I take exception.
He should have said the gutter culture of single parenthood, which is totally devoid of virtue,
is destructive - not single parenthood.
My sister was made a widow when her two children were young and she has done an excellent job in raising her two children alone like you have. She does not exist in the gutter culture of producing babies w/o dads. Neither do her children.
