The International sign of co-operation is a rainbow flag, because it contains all the colours of all the flags of all nations - I have one outside my door - (not on a flagpole). It started in Rochdale because the workers were given flour adulterated with talc so they formed the Rochdale Pioneers and set up their own shop in Toad lane to supply good healthy food and demand better wages.Also no one with money
can order a rainbow they are for us all and cone and go with weather changes nothing to do with us. But its a real pleasure to see a double rainbow!

no. i also don't need a box.

I’m showing my geek flag. I always wanted to be a part of this.

Not to rain on your parade, but I don't see any need for a flag and even if I did, flags are for countries and tribes and organizations, which atheists and agnostics simply aren't. Both labels are definitional concerning some very singular and narrow knowledge and belief positions. Philosophical positions don't have, or need, flags.

Also, efforts to bring unbelievers together organizationally are by any objective definition an abject failure, for precisely the reasons just stated. If, say, an atheist is definitionally still an atheist if they hold any belief or engage in any activity so long as they lack any belief about even one deity, then getting them to agree on any group identity broad enough to hold together an organization such that they'd need a flag, are pretty much doomed to be stillborn.

No plastic. Should be biodegradable.

Any such flag should contain elements that convey intellectual honesty and moral responsibility.

Hi

If we have to have a flag:

Fish with feet

Or

To my way of thinking flags are divisive and nurture an 'us and them' attitude. I'd rather concentrate my efforts on the long slog of bringing people together. (First person to say 'kumbaya' gets nailed to a cross.)

Here's a candidate

Interesting thoughts but think I prefer to be incognito that way no one can snigger- I don't actually like the idea of 'pride' I understnad it from a gay persons point of view but given that I have never had a god ever it doesnt appeal to me to 'out 'myself in any way - I fell like just any old regular person .A bit like groucho Marx saying he wouldnt belong to any club that would have him. Sorry .

That's not a bad idea. Maybe something that reflects our place on earth, within our solar system, and the galaxy. Stars and stars and stars, with no stripes. Or a stylized image of the Milky Way as seen from earth, or perhaps as it might appear from afar.

I'm gonna go with white.

What? No! Why on earth would that be necessary?

Maybe of a round planet earth.
Or something Science biological

No thanks. I have no use for flags. Knock yourself out though.

Nothing.
