The truth is that one Priest, Mohlomi Makobane, commited a grave sin in violation of Canon Law for giving Clinton Communion and he was disciplined for his mistake. Were it not for the outrage of the "they" you so casually mentioned in passing, Slick would have been given a pass.
See my follow up post for the explanation as to how the whole episode played out. There was the initial Pooh-Pooh given by the weak kneed American version of Catholics. There was also an initial silence by the Church leaders in Rome if you remember. It took about two – three days for them to find their voices.
I still want to hear how they justified making the four children of Teddy, the killer, Kennedy instant Bastards.
