Forget it?
That sounds like forgetting about the fact that your wife had an affair with another man, so you can continue the public pretense you are "happily married".
Or forgetting to warn the next parish where you move a pedophile priest to, that he has a predilection for 8-12 year old boys. 12 months later he is heading up the summer camp.
Is the Church indefectible and protected from error in its teachings or not? Forgetting the bad councils does not suggest it is.
I'd like the paradox last sixty years explained, not forgotten about and swept under the rug. Write down a complete history, expose the corruption entirely and let the chips fall where they may.
Saying, "let's just forget it" honestly makes me wonder what has been forgotten about in the past 2000 years.
