Specifically, what aspects of your culture would have to change to make atheism more

What can people do to enact that change?

In the U.S. we need to be more secular, as our founding fathers meant for us to be, instead of giving in to the silliness of Christian bible belt parents.

Ok... while I think I see what you are questioning, we might give you a more thorough answer if you type more info. Just edit some and I will come back! ;p

More education.

were getting there. a few hundred years ago they used to burn us alive. now they only complain and bitch about us

Ignorance is never more acceptable than knowledge.

A culture where people actually try to understand each other, rather than merely just tolerating their coexistence.

Australia is fine by me?

In order to make atheism culturally acceptable where I live, in the US, we would have to kick out all the political figures that are pushing theistic views into laws.

Once the theistic crowd loses that chip on their shoulder of having things their way or no way atheism will be more culturally relevant.

I think it is becoming more culturally acceptable, but I don't ever see it becoming as culturally acceptable as homosexuality. Religion plays too big of a role in society... unfortunately.

Atheism is the height of spirituality. Unless you say no God, you can not bring people under one roof of one God. Kill all Gods, all religions if the religions can not teach universal brotherhood.

My country and many of the surrounding countries are now largely secular. Many people still use religion for important rites of passage e.g. birth, marriage, death. But, on the whole it has lost it's value. Culturally, you have to start slowly by challenging anyone who claims to represent the people as a whole and then uses narrow minded doctrine to make unjust laws. Politicians, media and other public representatives must present an impartial approach to their laws, policies and opinions.

P.s. It is completely acceptable to be atheist here.

The overriding view that if you believe in a God you are inherently good, a much better, nicer and more trustworthy human being than those who do not believe. People should judge people on what they do, and not what they say. It's shallow and pathetic that people think themselves and others inherently better because they say the words 'I believe in God'. Our society is one based on status, and most people seem trained to bow down to that anachronism.

getting better teachers for everyone

education is the answer

I live in Scotland. For atheism to be more culturally acceptable, more people would have to care about religion in the first place.
