I don’t think that all judgements are bad - I know Jesus said “judge not” but he meant keep from making judgements without knowing facts. How else to know good from bad if judgements can’t be made?
The veil I think is supposed to “show or signify” reverence for humility and the woman wearing it may have seemed dignified, so the poster made their judgement based on that. But without knowing what’s in this woman’s heart, you can’t really know for sure what her message may have been with the veil-wearing. I think you can judge as to what this woman may be trying to “say” by wearing a veil, but if this woman isn’t interiorly (is that a word??) harboring humility and dignity then it would be her sin, and that’s a cause for our pity. We’re always supposed to expect the best from people in the name of charity rather than jump to bad conclusions about people and their actions, just a reminder than I too need on occasion!!
But I don’t think it’s up for us to judge, one way or another, we should just acknowledge it for what it is - a sign of a devotion. I know I try to do pious acts at Church during Mass for my own growth, but also a little bit to try to bring back reverence for the Mass in other people. You may think that’s “holier than thou” but I don’t judge people for not being reverent, as maybe they weren’t raised to be reverent, they don’t know why to be reverent, I have no idea. But if I can get them thinking about what I’m doing, why I’m doing it, maybe they’ll check it out for themselves and wil be drawn to giving more reverence for the Eucharist, etc. Or maybe they’ll judge me for being pious in a bad way, but that’s their problem, not mine, and God knows my heart so that’s all I’m concerned about.
Hopefully that didn’t sound harsh, I’m just trying to explain, although I admit probably not in the best way, to help you understand what may make people seem outwardly pious.
Hope I make sense!!
