Who has the responsibility?

Virtually any criticism of the president is called racist, whether parody, cartoon, jokes or telling the truth. And I've seen some that truly are racist--and they are sickening. But which is worse--some flake on the internet saying nasty things about a black president, or a black president thumbing his nose at the Constitution, traditions, and Congress while the media and his supporters swoon in admiration? Which person has the greater responsibility and the bigger bully pulpit?
