The moment someone attacks another person's character rather than the arguments, you know that all civilized conversation is not possible. I would strongly suggest against humoring that type of people.
The man is successful enough in his endeavours not to need "me" to defend him. One last thing though, his voice, well, he was very ill for a couple of years and he was literally on the verge of death, so taking into account he made it out of that and is still touring, speaking up despite the threats to take his medical license speak volumes more and shows more accomplishments and coherence than everyone attacking his character would. And that's all I have to say about that.
Back to Maimy, the thing about any mental illness is that it's mostly invisible to the outside world. The guy sounds like a complete tool, but until she stands up for herself and becomes strong enough to seek help outside, she's stuck and the outcome might not be good. Wasn't there a scandal about Amouranth's SO being also an exploitative tool? My conjecture is that their partners stopped caring, loving and respecting them long ago. They opted in towards becoming pimps, because once again, "high value men" are nowhere near thots. The only leverage and bragging rights their partners have are... I get to fuck this chick when there's literally thousands of men who would do unimaginable things for the chance to do it. Ohhh and tons of cash, but I wouldn't be surprised if they have "side chicks" (or actual GFs) that are far away from the industry. Personally, I wouldn't like to have my girl's goodies on full display for the world to see.
