I get the argument, and I agree with much of it. But the author loses points with me by using the term bastard, and derogatorily at that.
Implying that a child born out of wedlock is of less value than one born in wedlock is silly. It reduces to judging someone for something wholly out of their control, while at the same time yelling, "Marriage (hence Church and Government) good! No marriage bad!"
What an antiquated mentality.
