**As others have pointed out, the homosexuality in and of itself is not a problem. If this Priest were to appear with a girlfriend, and declare he was an active heterosexual man, advocating for the Church to change “backwards dogma on married Priests,” we would have a similar dialogue going on. **
What the media will probably forget here is that it doesn’t matter whether you’re Hetero or Homosexual, Bisexual or Asexual, Backside down and up to front, any colour of the rainbow or otherwise… This Priest broke his vows. Not just privately, but publicly applauding his decision to make himself a God and suggest the Church ought to follow his perception of reality (and that of much of the general population).
We all know it is a mortal sin to encourage others to engage in sinful activity, no?
We all know that this was timed with the Synod, as a subversive move to derail the proposed dialogue. Now I don’t think that is a sin.
Now, had this transpired in private, and he was “revealed” as a homosexual (or otherwise), I’m not sure whether he might be subject to review to ensure his pastoral practices were sound, or not.
In any case, publicly teaching and advocating against Church doctrine is heresy - and deserves both strict and immediate rebuttal, if not excommunication, depending on the severity.
