What do the ladies here have to say about this?
This lady says you have too much time on your hands. Instead of searching for offensive photos on the net, when you see objectionable attire at church, AVERT YOUR EYES and say a short prayer for the person.
Everyone is in a different place on the road to eternity. Pray they will follow the example of more devout women at Mass. Be thankful they are at Mass to get the graces they are in need of to change their wayward inclinations.
At Mass your attention should definitely be elsewhere.
Let the women take care of the offenders.
