Ukela – someone’s mad

I spotted this sign on Guadalupe Street and then thought “Duh, we’re all human. Pastors & priests make the same mistakes everyone else does.” but someone was angry or hurt enough to spend the time and make a sign & post this warning. I’m curious about the story behind this sign & since there is no author… my imagination runs wild. 

Oh, the translation, “Pastors and priests are false. Investigate.” Hmmmm… what’s the story, what’s the story…
