Because their faith is not enough. Plus, they know their God isn't the same as everybody elses, certainly the three Gods of the Abrahamic schisms are not the same, ... but they are loathe to admit that, ... so to cover up their own misgivings, about not accepting another theist's credo, they instead bash atheists, while being guilty of exactly the things they accuse us of, but towards other faiths.
That, is irony.
On the contrary, I think, by posting these threads, theists are practising their religion in a very freudian manner. They feed on it greedily. They need atheist bashing to reach some sort of a climax.
It's a common public sado-masochistic sexual relationship. It's legal and safe. In this case the masochistic part (theists) tease atheists with embecilic dogmas -any of them can drive an avarage intelligent human mad- and get their dose of turture and abuse for their required extacsy.
I mean, *chuckles* look at the title. The Nonsense of Atheists=Come and hit me. Lol, I am tempted to ask for the safe word.
Atheists are by nature critical, argumentative people. They don't put up with crap. They would point out any holes in any idea, not just in religions or theism. They are loud and they have to be bold to a point to clash with the old world systems and the 95% of the planet. They are characteristically dominant people.
In this forum, I have seen many theists and atheist clashes.
One thing never changes. The theist or the religious freak telling his/her god found moments over and over again, replenishing the source of faith. And when slapped by an atheist, they start defending their delusion fervently, they provide themselves a position that imitates an altar to let atheists (demons) to torture them and thus make them more holy or righteous; more saint like? and so delivered.
I don't get in to any discussions with theists on the subject and mostly -not all of them- they don't contribute anything to the forum. You can see them in the sort of this threads.
I also feel uncomfortable because either they suffered from drug or alcohol abuse, lost somebody, had an abortion and stopped slutting around (instead of using contraceptives and what technology offers, but they all have computers and cell phones I am sure) and so on, which are certainly personal experiences could make a human suffer. Aaand they meet Jesus, Mohammed,Zeus,Abraham,Kali,Kybele...Buddha, whatever.
So these threads are some sort of warm shells and mediums for little martyrdom moments without death. And the internet is slowly becoming the vast combination of cathedrals,mosques,sinegogs...temple of these people.
Well, that's what I think.
