Because it serves a genuine function, because the process poses an unnecessary risk, because there is no way to know how big the penis is going to get when the kid grows up, and that is part of the reason for the foreskin, to have a ton of give so it doesn’t happen like it did to my ex. He got circumcised as a newborn, and by the time he finished puberty, his penis grew far more than the leftover foreskin, so he wasn’t even able to have full erections without a tremendous amount of pain and sometimes, even tearing.
Honestly, I agree with you and with them. They chose said painting because it is incredibly expensive, so it represents how much people are willing to pay for a painting, while not doing an effort to care for the world we live in.
According to my sources, another reason was that the painting was encased in glass, so they saw it as a great target for the stunt, to get attention, while not causing any damage to the actual work of art.
So, the message being “Look at how much you people’s care about us “destroying” a work of art, but nobody gives a shit about the people who are destroying the world”.
