Christianity has had 2000 years to make the world a better place.So the christian cult is the majority? Well that explains the vastness of Internet porn, strip clubs, bars, pedophiles, murderers, rapist, thieves.
Most people who do not believe in "god" will claim to be christian when confronted in public about religious beliefs to avoid persecution. The number of people who go to church at least one day a year makes the christian cult a very small minority.
The true number of "christians" is about one fourth of the claimed number.(even most Satanist will lie and say they are christian to avoid losing their jobs and having protesters outside their homes)
It's time to try something else.
