I have read the article you posted Dick. Welcome to the site and your first attempt to find out way in the virtual world of cyber space. No one expects your first foray to be a success and it is of no surprise therefore that as expected it was not. I look forward of course to future attempts.
I think your mistake lies in the notion that such a thing has not already happened. A lot of people here are in fact active in meatspace and not just cyberspace.
You see when you are, for example, a Christian you can join under a banner as you all know what you all believe in and the basis for your world view. There is a strong and common theme upon which you can all unite.
However with atheists there is no connecting belief just a connecting lack of one belief. The notion of forming a political party with them has been likened to herding cats. Their non belief is common and their wish for a secular political scene is common but after that there is no common belief. Atheists by nature tend to be individually opinionated and inquisitive to a very high and strict degree. As you can see from this site we often disagree totally on issues like homosexuality, abortion and even the naming and shaming of sex offenders.
So rather than getting together under one association we are instead spread like a seasoning over other associations and other political fields. Sometimes we meet shoulder to shoulder fighting for an issue, while sometimes we find ourselves sitting glaring at each other from opposite sides of the table.
The only unifying concept in these situations among us is that any argument we put forward to support or attack each other will be based on real evidence, reason and demonstrated studies and statistics. We will not in any of our dealings appeal to higher powers or invisible sky fairies.
An atheist can be a republican, conservative, liberal, an anarchist, a nihilist or any other category you care to name. At the point you realise this then the false premise on which you base your consequently false article will be rectified and you will realise the error behind the essay.
Also since you are not aware of the real names of the general users of this site your assumption that they are not active in meatspace is just that… an assumption… and one that is therefore based on no evidence whatsoever. The moment you make assumptions about your antagonists is the moment you have already lost your debate.
As I said, better luck next time and I look forward to your next offering to the site.
