They would never do this to Muslims.
They wouldn’t do it to anyone other than Jesus. And really I don’t think it is Jews and Muslims behind this - at least not on religious grounds. I would bet good money these are atheists regardless of their heritage. I just don’t understand why an atheist would be offended by a painting of something they don’t believe in. If the academy had the original Goya painting of Saturn Devouring his Son would they complain?
