Being an Atheist is as important as being honest sane and neighborly. I was born this way and cannot imagine living my life any differently than Atheistically......I will not lie for 2 rapist popes, be irrational as bible thumpers nor threaten anyone with alleged hells nor bribe others with alleged heavens

No.

Being successful in life is. If you do that as <insert belief, or lack, system here> then more power to you.

What is important is that you are happy and healthy. It is totally unimportant HOW you go about doing that.

Yes.

If you want people to know who you are and if that is the truth about you. Let it be known.

Is the fact that it is raining or not, important?
Based on logical contingency I would have to say yes.

i try to avoid all isms when describing or introducing my self. i see my self more as someone who doesn't tolerate bullshit.

Not if it is unnecessary, I don't tell people many things.

No. Being human and respectful of other's thinking is much more important to me.

Not too much.

I'm mixed on this one. Ultimately, I'm more an agnostic leaning atheist. I'm not totally "out" I guess. So for that reason it is hard to know.

Only when they insist on religious conversation or stepping on other people's beliefs. I don't run up to strangers and tell them I'm an athiest because that's not the only thing that makes me me. It's just a part of who I am.

My lack of faith is not something I generally advertise.

The label is not important. What is important is freedom from slavish devotion to religious ideology.

Not really , the beauty of being an atheist is that it doesn't consume enormous quantities of time .

Not the general public. Perhaps people you work with and people you live with.

Personally, only if people ask and argue. I generally let people believe what they want. I try not to judge people too much because it's a free country, and lately I've not been pestered because, though people may not understand, they understand I don't judge them.

About as important as not believing in the tooth fairy.

Is not a matter of "being important" but of you feeling it's being important to you.
