Me Myself

If people don't want people to read their shirts or look at their tattoos, then why would they wear them or have one? It reminds me of people in the 80s, who would grow 2 feet hair, cut into a Mohawk and dye it bright orange and not want anyone to look at him/her strangely. So, I vote morally neutral.
Maybe they wore a random t shirt, unexpectant someone would take notice of it to the point he would try to read out the letters or figure out the figures (some of those are really abstract!)
