Why do Christians say that ancient civilizations are disgusting because their art shows ual acts?

Yeah! Like there are no bigots, sodomites and degenerates around these days! Having said that, it's only the extreme religious fruitcakes who would look upon ancient cultures that way. Generally people simply accept the ancients for what they were. And anyway, the ancient Christians, and their precursors, were hardly nice, decent, clean living folks themselves! The Christians were, until fairly recently, the most intolerant, cruel, murderous people around. Having said THAT, it's not the religion, it's PEOPLE! Human beings, being what they are, are capable of absolutely ANYTHING!
