Another bit of ad hominem on your part.  First, no anger, but originally there was a period of dissonance and righteous anger upon discovering the scandal of OD's status and unwillingness of too many in the Church to investigate.  Don't be afraid to encounter that yourself.

But let's address the issues again.  Getting back to the original topic of Oscar Romero, it is really a non-issue if he had a positive view or even friendship with particular priest members of OD.  I don't judge them or any fully-committed lay volunteers like you who intend to encourage others to virtue, etc.  Romero's perceptions at that point, like any other representative of the Church, do not constitute an endorsement of every unseen action.   

Please investigate the readily-available information about OD's problems.  The vast majority is not "anti-Catholic" or ridiculous DaVinci code fiction.  Most of the others who appear to be fallen away are indicative of residual psychological damage and scandal.
