Joe O made this observation awhile back on another post:
".... in many dioceses there is a strong homosexual culture among a certain small (but significant) faction of priests - in certain circles of priests, you'd think you were in the Castro District of San Francisco. Conduct is overtly sexual and flirtatious. "Straight" priests feel very uncomfortable in such circles, and can often seek friendship with parishioners instead of with classmates if this sexual culture is too strong. I would guess from the overtly sexual attitude of priests in these factions, that celibacy is not important to them. As I said above, there was a time in my sophomore year of college when this sexual atmosphere was very strong, and it felt unhealthy to me until a number of people were removed by psychological screening. While I was in the seminary, I did not know of any students being sexually active. Some did go on dates with women, but I never heard of male-male dating. I never, ever heard talk of anybody even thinking about having sex with children, or professors having sex with high school or college seminary students".

Joe's personal observations indicate a homosexuality community within the RC church (not surprising) , but does not indicate a link between those from the homosexua group within the RC church and the child sex abuse(I am unsure if anyone followed up on those comitting crimes, as to their sexual preference in society, after leaving the church).

I suspect some are confused as to whether the male sexual child abuse was in the RC church was situational homosexuality or dispositional homosexuality (see the attached link with observations on the prison homosexuality scene for the difference). If it was mostly situational, (as within prison) then could the impact of celebacy not be a valid theory?

Access to the complete document is not online. But the site does give one an idea of the observations....and possibly more rersources exist on the topic online.
