He was being light-hearted, Vulture, as was I.
I'm sorry if in the process you felt there was a greater depth to the use of the word bastard than the way it was used in this instance, but although illegitimacy (and if there was ever a term to take exception to it's that one) has suffered grossly unfair stigma by the hi-jacking of the word over the years, thankfully that stigma attached to fatherless children has all but disappeared these days, due to more enlightened attitudes, far greater things to worry about, and the crumbling of marriage as the norm. I guess some of that is to be welcomed, if not all.
The increasingly complex nature of relationships means that the word bastard is now almost exclusively confined to it's own very separate dictionary definition of a 'despicable person', and there is no hint of a crossover into illegitimacy in its common, modern-day usage.
That said, as someone who has on a good number of times wished he was one, I'm very sorry if the use of the word bastard in any context causes you pain, Vult, and I now regret my flippancy.
