What if it’s not? That Bernardin was an active gay has been well known for a long time. The rest may be debatable but Bernadin’s tenure in the USCCB was a disaster for the Church in the country, a disaster from which we still have not recovered.
It's a sin to bear false witness against your neighbor. You have no evidence whatsoever that would stand up to scrutiny. Does a long time include the time the Pope put him in office? Is the Pope gay too?
