Do you remember this from a few days ago? You seemed to be implying that Christianity sells itself on the strength of its message rather than through a millennia-long campaign to propagate it:
Kenny: "Propaganda" would be forgotten in 10 to 20 years - but the message has continued for millenniums
It Aint Necessarily SO: So has the propaganda. Look at the word and its root. People have been propagating this religion and its scriptures all of that time, sometimes at the point of a crusader's or conquistadore's sword, sometimes with missionaries, sometimes in Sunday schools, sometimes by putting Bibles in hotel rooms, and even sometimes advertising during the Super Bowl. Super Bowl ads will tout Jesus 'gets us' to the masses - ABC News (go.com)
Christianity is a business. It's how you support yourself. It's why there are as many churches as banks, gas stations, and fast food restaurants. I just looked at a list of Super Bowl advertisers praised for their commercials. Every one is a business: Sam Adams, Uber, Pepsi Zero Sugar, Bud Light, GM, Netflix, and Crown Royal.
