I'm not seeing the logical connection between athiesm and charity, and I certainly don't know if you could derive charity in an entirely athiestic worldview. Now, certainly there are athiestic charities, however I don't know if there is a connection directly between athiesm and charity. And certainly no driving force of it, I guess you could arbitrarily decide if it was good to donate to charities?
have atheists done anything for the good of man?

does athiesm lead logically to charity
Apologies in advance if you don't like my tone, given this media is far from my first choice. I would prefer to leave you to your way of being and encourage you to focus on growing the good in the world.
Comparatively you almost sound pro-thiest

I also knew someone who was beaten for his belief in God, although this was in a public school.
It takes all types of people to make a society. Looking at a simply breakdown like Myer Briggs Colours you see the general population divides up, and about 3% in general are more logically minded and they tend to think along the lines of reason and logic. It is through this lens you can begin to see that God is not a personal god, but actually a metaphor for the fundamental laws of physics. And why call him god anyway it is a delusion. (These are the inventors - problem solvers) typically called athletes
That's not a logically valid statement.
So dumbed down if you want a world run by non profits - get rid of the green and replaced with gold, oh and those tools you use (the wheel, metallurgy, the plow, the printing press, the internet, ) well there source is from the marginalized innovators.
Community work and altruistic contributions to society from the innovators abound today - you just need to know where to look - Bitcoin and other OSS is testimony to that.
I don't think anyone wants a world ruled by non-profits?
Further, bitcoin and OSS are all nice I use both (Currently running Ubuntu exclusively, with all OSS tools), however the goal of OSS as I understand it (feel free to reference material that says otherwise) is that many people together can create something better than commercial software, not that someone in need would benefit, indeed Linux has only rencently even become user friendly, it used to be a bunch of hackers attempting to create awesome software, usability left off to the side.
Bitcoin, as far as I know was not created for charitable means.
The belief that a cosmic Jewish Zombie who was his own father can make you live forever if you symbolically eat his flesh and telepathically tell him you accept him as your master, so he can remove an evil force from your soul that is present in humanity because a rib-woman was convinced by a talking snake to eat from a magical tree.
This is the type of thing I am speaking of, athiest use language like this all the time. Word twisting fairly rude, this is basically an ad-hominem attack more than anything else.
Athiesm:
The belief that the universe was empty, then it wasn't, then splat you have the entire Universe. Your ancestors are monkeys, and black people are racially inferior because they are more monkey like. Objective morality doesn't exist, so Hitler was A-OK as long as he thought he was doing good and didn't think the Jews were human. And really even if they were, we're all just molecules in motion. What if a pile of molecules stop moving, who cares?
