Atheists in America are constantly bombarded with religion in their everyday lives. We are confronted with Christians trying to push their beliefs into our schools, laws, and government. We are preached at daily. We are the MOST distrusted and hated minority group in the country. We're fighting a rearguard action for our rights here.
Also, if you guys kept your religion to yourselves, you'd never hear a peep from atheists. We couldn't care less what you worship if you just keep it to yourself! Leave it out of our schools. Leave it out of our laws. Stop trying to convert people. Just leave everyone else alone and we'll stop having to defend ourselves.
