Sounds like some disgruntled parishioners trying to control the priests. All of us know how that ultimately turns out.
Nonsense. Sounds like completely out-of-line behavior by the priests, who often try to set themselves up as little gods in the parishes, putting them in jeopardy by overspending (money they didn't have), disabling the legally-required fire safety equipment, subjecting them to legal jeopardy, and then ripping off the chapel on their way out. Typical SSPX behavior, and this wouldn't be the first time I've heard of such things ... typical SSPX bullying.
