I have been mulling over whether or not to post this since Saturday night and am only doing so now to stop myself going (more) bloody nuts (than I already am)!
A couple of friends, four guys and five girls, and I were having a drink in an almost empty pub and one of those silences that result from running out of things about which to bitch that we haven't bitched to death before fell upon us when one of the girls, well known for her frequent visits to porn web-sites, asked why so many of those performing in porn films, male and female, wore a crucifix around their necks but not the Star of David or the Pentacle or even a St Christopher.
To say that the ensuing conversation offered no sensible answer to the question would be a gigantic understatement.
I have not tried to check the veracity of the statement and have no intention of so doing, but the "WHY" is nagging at the back of my mind and I throw it to the assembled intellect of the Forum to see if anyone has an answer or even a possible reason for the phenomenon.
