If he is genuinely furious over the activities of the organisation in the thread title why is it wrong to launch idiotic attacks at it?
Detailed empirically concise posts may serve his position better but everyone here has farted into a thread dropped a stench of their opinion and farted out again leaving us all debating as to the merits of lighting a match.
If you discovered that someone was a member of some organisation that had gone out of their way to make money out of crime, cover up child abuse facilitated by the traditions of the institution : discouraged poor people from using a proven method for reducing the fatalities of sexually transmitted epidemic and also a proven method of managing family sizes beyond aborting existing fetuses ; while politically lobbying against other groups of people who happen to believe different things (all this after a history of torture, murder and repression) but wasn't the Catholic church, I assume you would make a very detailed account as to why you might think membership of such an organisation might be less than optimal.
I imagine other people would would just ejaculate.
Using the word "Church" or "Religion" seems to be assumed to be a shield against criticism. Shields however often make convenient targets.
