Philip the Fourth of Spain. Painted by Diego Velasquez. The Austrian Habsburgs had that characteristic under bite as well as hemophilia.
Then there was Charles II of Spain, aka Charles the Bewitched, victim of Habsburg inbreeding & the last Habsburg king of Spain.
Muslim inbreeding reminds me of Vincent Price in “The Last Man on Earth” where he is surrounded nightly by hordes of zombies. Physically weak and mentally stupid as individuals, but there are so many of them.
Too bad Muslims don’t wither in the sunlight.
