Atheism.

That somebody chooses to be an atheist is entirely a matter between them and God. They will ultimately - and tragically - find out the truth which genuine Christians have already discovered experientially in this life.
The propagation of atheism is quite something else. In spite of the pseudo-scientific protestations to the contrary - God CANNOT be disproved. Proving a negative is always difficult at the best of times and their problem is compounded by the fact that God does in fact exist.
In order to decry my personal and ongoing experience, they are forced to declare me, and indeed all born again believers, to be either liars, deluded or mentally ill.
The astonishing hubris, based on what is simply their guess versus my reality, is almost beyond belief.
With atheism now on the sides of buses to propagandise the terminally gullible over and above what has already been done to so many in their 'comprehensive' education, it is no surprise that Letters Pages on Ceefax and Teletext are currently riddled with a stream of dogmatic, atheistic ignorance and arrogance.
