Well, I’m not sure everyone is on the same page about baptism and plenary indulgences, but be that as it may, going to confession is good, showing mercy is good, and if the devotion doesn’t appeal to someone it seems that’s fine.
The presentation was from the Shrine in Stockbridge. I went to their site and found this very first post about the difference between a plenary indulgance and the special graces of Divine Mercy Sunday:
“4) The most special grace promised by our Lord for Divine Mercy Sunday is nothing less than the equivalent of a complete renewal of baptismal grace in the soul: “complete forgiveness (remission) of sins and punishment.” Such a measure of grace can only be received otherwise through baptism itself, or through making a sacramental confession as an act of perfect contrition for sin, out of pure love for God.”

However, on the plus side, they also say no Catholic is required to believe this as a matter of faith.
"This week, a Mr. Dwyer asked: What is the difference between the special graces promised by Jesus for devout communicants on Divine Mercy Sunday, and the plenary indulgence for Divine Mercy Sunday devotions that was instituted several years ago by Pope John Paul II? Are they the same thing? Or are they different?
Simply put: They are NOT the same thing!
The main difference, of course, is that an “indulgence” is something offered to the faithful by the Church, as the keeper of the keys of the kingdom, with authority to “bind and loose” (see Mt 16:17-19). The special graces of Divine Mercy Sunday, on the other hand, were promised directly by our Lord, through a prophetic revelation given to St. Faustina (see Diary of St. Faustina, 699). The Church has not officially ruled that this particular promise was an authentic supernatural revelation (and no Catholic is required to believe it as a matter of faith), but the Church has discerned, in various ways, that there is nothing that violates Catholic doctrine in this promise."
I hope it is OK to post those quote since I reference the link where they are.
If the Church said it’s not harmful, then that’s good.
