I don't believe there are any real Christians, forget about condemning gays with gray logic and stuff that wasn't said and look at exactly what Jesus thought about money. It isn't really compatible with capitalism if you know what I mean. The moral of the story is to avoid being one of the "F's" in FFF investment opportunities. If these players want to have money when they are facing post-retirement debilitation, they should stick to low-cost index funds and not look at their portfolios very often. There are plenty of cautionary tales about retired NFL players who lost it all.
Faith based scams are troubling than other varieties of scams simply because they prey on people's faith. It's manipulative and dishonest, and can oftentimes not be perceived as "too good to be true" options because of the method by which they are appealing. It's a dirty trick used by those for personal gain.
When a scam engages a person's faith, it attacks him or her at the very core. Utilizing faith to make money is concerning not only from an ethical standpoint (potential one way ticket to hell), but also from a humanist standpoint-- if you manipulate a person at their most vulnerable and honest, you run the risk of stealing their faith in humanity along with their cash.
No, faith-based scams are not more troubling than other varieties of scams. In fact, faith-based scams are less troubling than other scams because most people can hear that these types of scams are scams to begin with. The fact that the people who are taken advantage of by these scams are members of the faith clouds their judgement.
