Personally, MLM is similar to hypnosis ... trying to change people's outlook on life or thinking. ...

The brainwashed person feels that everything has changed too much, especially his views ... he is super confident ... but most of his brainwashed views are flawed ... Pay attention to finding out his loopholes, and directly, concisely and fatally refute them, which will hurt his confidence. Don't back down, because you are right ... If you back down, he will think you are wrong (there is no way ... he is crazy about pyramid schemes ... too confident ...) and try to let him know that you are doing it for him, instead of telling him: Oh, I am doing it for you ... I don't listen ... Try to live in harmonious point, eat delicious food, have fun and give him more smiles. Soft and hard, you can compromise and accommodate him on other issues, but not in MLM! As far as attacking him is concerned, try to change the subject when there is conflict (when you are young, old ideals, etc.). )

And as upstairs said, read more reports on cracking down on pyramid schemes and give him more good books to read. ..

But I know it's hard ..

The above, personal opinion, is for reference only. ..

I hate pyramid schemes, too. I hope you can get out of the shadow of pyramid selling and live a normal life.

Finally, good luck!
