Public displays of religion are the OG form of virtue signaling

Wearing cross necklaces, wearing saint cards, telling others you'll pray for them, making a scene out of public prayer over some chitty T.G.I.Friday's meal, publically thaking God for anything good in your life while ignoring all of the horrible things in the world, etc. All of that crap is purely for attention and trying to attain a status of people thinking you must be some supremely good person.
