For many years, we have never heard about any of the great Egyptians artists who used religious or moral discourse? The answer is simply because they were real artists who had real talents.
Their work became masterpieces in our modern history and some of them reached international level. Thus, they didn’t need to use religion to gain the respect of their audience.
This gives us hint about many artists who don’t have great talents and try to trade on religion to appear as respectable as much as he or she can. Our community has been marked by fake religious identity that doesn’t fit good art. Only great artists live through their lasting work.
