I was a member of a church once, where the pastor got suckered into MLMs sometimes. He didn't sell them to members outright, he had more integrity than that. But in that church many people got the idea that MLMs were somehow legitimate, so there were a number of those stupid things going around. I just want to slap people that are so naive and stupid, and are old enough to be my parents (in their 50's) and should know better. They also got caught up into a number of stupid Alternative Medicine hoaxes- like those stupid laundry balls, and various gadgets to "align your energies", and the whole Hulda Clark "Cure For All Cancers" LIE. The whole "Western Medical Establishment is evil and Keeping The Truth from you" thing. One church member believed that line so thoroughly, that when she developed cancer, she refused to go the Western Medical Route whatsoever, despite the advice of most everyone around her who told her to see a regular doctor, even the New-Agey woman who brought that fiction I mentioned there in the first place. She spent her last days traveling around the country, trying to find some alternative medicine "cure". They spent a ton of money on this, and finally came home to die. The cancer had eaten through her. I am told that she said she wished she had had the western medical treatment in the beginning- and she would not have died. She left behind a husband and three children. To me, those Alternative Medicine hoaxes are just the same kind of lies as MLMs, and worse sometimes.
Another forum I know of is run by a pastor, and he and a member of his church both do this one MLM, I forget which. They actively push it on that forum, its disgusting.
