You don't vanquish error by allowing it "just a little bit of room", Holy Father.
You vanquish error by not allowing it *ANY* room. None whatsoever.
Look: I understand compassion. I understand mercy. Really, I do. But no matter how much compassion you feel for someone in error, you can't approve the error.
Should the Church approve blessings for people who siphon gasoline out of cars because they're too poor to buy gas? I mean, after all, they could have stolen the car, but they didn't. And because they're so poor, allowing them to swipe the gasoline is compassionate, no?
How about if a religious order decided to devote one day to worshipping Baphomet instead of Christ? Should the Pope bless that? I mean, hey, it's just one day; the other six they serve Christ.
Do you permit this "just a little bit of error"? Or do you recognize that "just a little bit of error" leads inevitably to "a little bit more error", and "a little more error", until you have a full-blown apostasy on your hands? Do you recognize that we face a malignant and dangerous enemy in Satan, who constantly looks for tiny cracks, tiny wedges, in which to insert his tentacles and gradually work for the destruction of the whole edifice?
And Lucifer is patient. If it will corrupt mankind, he takes just as much time as he needs to get the job done.....which is why we cannot allow him any advantage whatsoever. We must constantly be alert to remain as close to Christ as we can, and to not allow any room for Enemy to use to his advantage.
