Atheists: do you reject all higher authority?

I just reject invisible ones that religious fundies try to brow beat me with.

Yes. I don't need strict laws to keep the peace or detailed codes of conduct from the divine. If I did it would imply that I'm so weak and inadequate that I need a strong master to tell me what to do or else I can't be trusted to be skillful or good. We don't need rules from the divine to tell right from wrong. An action is wrong if it causes unhappiness for yourself and others either now or in the long term. An action is right if it makes yourself and others happy, pleased and content now and in the long term. If atheists were more immoral on average than theists then the United States should have the lowest prison population on Earth since 75% of the population is Christian. This is not the case.

No, the government is a higher authority than I am, I don't reject that

That is a very strong word.

I simply refrain from following those individuals and institutions of authority which I perceive as unworthy, unreliable or unnecessary, following my conscience and empathy instead.

But alas, such has nothing to do with me not believing in a god or gods.

I simply cannot force myself to shut out everything else and pretend that I know with absolute metaphysical certainty that there is, put very simply, a spellcasting creator who made everything.

It is intellectually dishonest - I acknowledge the possibility, as I acknowledge all other possibilities, but to assume that I am correct and move on to convert others, as many religious and non-religious do...

...I shall not.

I admit this is no answer to your question, and I am not an atheist, but, man is the only life form stupid and cowardly enough to allow anything to have life or death power over him. Authority is a predator that denies you the right of self defense before it attacks you. This makes it not only mans most dangerous enemy, but also defines the words cunning and coward. Should any man respect the enemy of God, mankind, and freedom?

No, I just reject ones that there is no evidence for.

I place the existence of God in the same category as the existence of leprechauns, invisible pink unicorns and Russel's teapot.

No, I accept accountable authority that actually exists, e.g. the law of the land and those who implement it.

Maybe if I lived in an unaccountable dictatorship I wouldn't, e.g. a theocracy or other totalitarian state.

Nope. There are plenty of authorities higher than myself. Thing is, none of them rely upon a whole bunch of 'so you say' as the sole evidence for their existence.

I would have had a hard time in the military if I rejected authority.

I happily accept competent, sane, authority.

NO .. if the 'Higher Authority' exists I accept it.

Nope...only God. But I have a bumper sticker on my car that says "Question Authority".
