I don't care for unsupported assertions that make the community look bad. Assertions such as the old "subliminal advertising" urban legend. Subliminal images in advertising have hardly ever been used, and they're hardly effective in tests.
When you look objectively at this situation and realize that none of you are seeing the same image, but you all are seeing nefarious things, you have an opportunity to step outside yourselves and learn something about the way the mind works. You've already been given the link to the Pareidolia article to learn about this trick that the brain plays on us.
The black man's arm that accidentally looked phallic also looked a lot like an arm, as it so happens. He was either replaced because the JW used as a model was DFed or because people kept saying his arm looked like a penis. That doesn't mean it was intentional. Do you really think the brother who painted that was willing to risk his livelihood at Bethel to sneak a massive phallus into his work? Think logically. The average age of the painters is probably 50 or older, last time I was there.
You know, the Art department is not a mysterious place full of shadowy figures. It's all laid out in the open, with small offices for each painter. The brothers are assigned a subject and they start off painting it the way they like. Then they receive notes from a supervisor who is humorless and orthodox and who may tell them to adjust some parts for doctrinal or prudish reasons. No one is telling them "Hide a goat face here". The idea is laughable.
This is a well-known reaction that occurs when people are resentful of those in power and make bad-faith assumptions. People who have worked in government know how unlikely most government conspiracy theories are. The biggest adherents to those theories are the people who are furthest from the center of power and know the least about the subject. The same thing is occurring here.
