AOG - "Or perhaps you are suggesting that homosexual acts are defined as sexual abuse?" - we are both too old and experiened for you to lob that bait into the pool, or for me to rise to it!
No, I do not know for sure that he is confirmed as an abuser, but his belated 'apology' and effective dismissal do tend to indicate that all is not as it should be - innocent people do not lose their positions and apologise for their conduct if not required. But I am a firm believer in innocent until proven guilkty, so i will retract that part of my post.
If his partners volutarily entered into sexual acts with him, that again is not the issue.
The issue is one of galactic-proportioned hypocracy - to live and work as a cardinal in the Catholic church, which preaches that homosexuality is a sin against God, and to speak out personally against it, while conducting homosexual acts behind closed doors is cant of the highest order.
This man should be throughly ashamed for lying to his church, his colleagues, and his congregation, and he should never hold a position of authority over others again.
