I have mixed feelings on the whole Mumei thing.
Firstly I think GAF is too far gone for it to make any difference. I mean even riskychris would be like "Whoa guys chill out." a long time ago.
I think he's well intentioned but has let himself go too far into the rabbit hole.
I remember one thread where I dared say that getting pass out drunk in public was a bad idea and even more so around people you didn't know. He took it to PM saying "I thought you were cool." and chastized me for perpetuating rape culture.
The reason I brought it up is because I used to work with male rape victims and one guy I worked with got raped when he was pass out drunk. And I'd go with him to these speeches he'd give about drinking responsibly and he'd just get it thrown in his face when he'd bring up the rape thing. When really the guy was just saying be on your guard. Of course all that didn't matter, because I dared say something out of his expected line I was practically dead to him.
I also make the joke of "give a list of 20 books" but that's not really a joke. I remember one thread he listed (I counted) exactly 22 books that everyone should read on this one very specific subject. It just boggled my mind. I don't have 22 books about a single subject let alone a very specific one. Like I have more than 22 books on history, but I don't have 22 books on Northwestern Chinese Horsemanship in the 12th century.. It seems to me if you're willing to read yourself that deeply with one skew you've lost touch with how the average person sees it and a little out of touch with reality and put yourself into the ivory tower.
Reminds me of when I met one of my techy heroes at a conference and he was giving this speech that was all wonderful and all but so disconnected with how reality actually worked in businesses and government, and painfully so. I mean anyone with even a year's experience would be like "That's nice but we live in the real world." I saw that he had spent so much time reading about technology and writing about it, that he had this imaginary world where it was as he read and wrote and had lost touch with how it is and anyone pointing to the contrary were just dumb people who didn't understand.
