You'll find the Atheists fall in two catagories.
Conversely, you'll find that atheists, (as well as agnostics and those who are non-religious), fall into several more catagories than the two disparaging ones which 'blindjohnnie' as pulled out of the air, (or, a much more distasteful orifice of his).
The First are the ones who are pretty aimless in life.They kinda followed whatever their parents believed at first.
Those tend to end up being the ambigiously-vague religious adherents or, they go on in life to decide what ethos to aspire to, (or, in the instance of fundamentalism, what blind faith to lose their sight to).
Then they go to college,and some professor lights them up by showing them all kinds of myths and legends.They end up with a superiority complex in which they feel the need to show others how primitive they are for believing in God.
Alternatively, they go on to college for the opportunity to acquire the ability to discern
from reason. Some acquire such abilities with or without a college education and others become fundie xtians who lack reasoning abilities.
The second is the "former" believer who basically "lost" faith.Usually this happens because of a bad situation or an illness.When their prayers are not answered to their satisfaction,they become bitter and end up blaming God out of existence.Also,some are those who have been mistreated by "supposed" Christians,and take it out on the whole of Christianity.
There appear to be at least a few of that 'type' however, there are far more xtians who cling to their blind faith despite repeated demonstrations, (like the ones listed above), that it is unfounded. There is no evidence whatsoever to support those sorts of things being a "test of faith" or, anything other than a test of one's personal character. What that tests is whether one is the sort of person who shifts personal responsibility onto others, (including "g-d"), or, not. If the former, they're more likely to be a religious adherent. If the latter, they'd tend not to be religious.
I suppose there is also a sub-set of those who simply resent authority and don't want to have religion's "rules" prevent them from having a "good time".
One catagory which 'blindjohnnie' is apparently unable to see is a completely different "set" of people who have their own personal code of honor/ethos which does not rely upon superstitious religious beliefs to be ethical and personally-responsible. What 'blindjohnnie' seems to be directly implying is that, without such 'religious rules', he'd be running amuck. If so, he may be blinding himself further by failing to realize that secular legal authorities would curtail his amuck-running by force, if necessary.
