one of those religious nuts who go around knocking on peoples doors
Preaching on the internet is much better and less nutty. And yes, that pun is intended.
If God hadn't helped me out
Only ... God did not do that. Thanking God for your own actions is the same as blaming God for your own actions. You shift responsibility.
You found faith and overcome something that you lost control over. Well done. But please do not infer from that achievement that the teachings of that faith, and more importantly, the interpretations from bigoted fundamentalists of that faith are sound or would help other people.
In case you did not realize, the bigots cherry pick parts of the Bible. Some examples that are generally ignored by the bigots in daily live:
You shall not wear a garment made of two kinds of material.
No eating of shrimp, crab, lobster, pork, rabbit and other things like blood. No mixing of milk products and meat products - no cheeseburgers!
Do not cut the hair at the sides of your head or clip off the edges of your beard
No work, travel, cooking, or business on the Sabbath
In contrast, there is plenty of naughty stuff in the Bible that is "approved", including prostitution and incest. The bigots arbitrarily ignore or emphasize portions of the Bible to push their own agenda.
Porn is NOT healthy
Being addicted to porn is not healthy. But being addicted to anything is not healthy. Being addicted to self whipping is also not healthy, quite literally and bloodily so. Yet there are those flagellants.
But alas, even if there were a bit of unhealthyness, it is proven without doubt that alcohol is unhealthy and can kill. Yet is alcohol forbidden in the Bible? No. It is not. Let that sink in. Only the overconsumption is discouraged. You can't very well forbid something that Jesus is well known for. Turing water into wine and all that.
