Why do most atheists on YA mention Zeus so much?

the guy does not deserve publicity guys, Hades is his elder brother and therefore it was his birthright to be the king of gods, Zeus refused to accept this and so made them all draw lott's (Poseidon included) to decide all their fates. Hades got the short straw and was demoted to ruler of the underworld, Poseidon got the seas and Zeus became king of the gods. Basically Zeus is a c**t mention Hades
