my friend made it known that he was made uncomfortable by the image in my signature. Does anyone else have anything to say on this matter?
They're trying to make people see phantoms, in this case, buying into Freudian theory, which is bunk.
I'm not saying hidden images never happen. Thinking back to when I read the secular children's magazine "Highlights" as a kid they had a game were you were supposed to find all sorts of hidden images. It makes me wonder if the people in charge of that magazine aren't aware of embedded images in famous art.
Looking back, "Highlights" strikes me as something that could be run by masons. (well, people obsessed with secular education of children and psychology, anyway)
However, what the Freudians want you to do is to see things everywhere whether they are or not.
They want to damage your thought process, not make you more perceptive.
So, no, don't worry about it.
