But that works in all directions. There are many kinds of people who cannot work together. I for one, despise the "lets all be friends and never say a bad word" crowd. They drive me mad and drive me to leave. I'd rather have a frank exchange of views with someone.

In the toxic positivity sense, "please don't be vulgar", or something else?

There are many variants. "Don't be vulgar", but also "don't criticize" or "invent something positive to say, only then can you criticize". "Be lavish in your (insencere) praise".

All this leads to a (despicable to me) culture of always-smiling emotional liars. If something I did is shit, say "it is shit". Make an unhappy face. Don't smile, praise my performance when cooking coffee and on the side mention that my last project "made some people somewhat happy".

But I'm not sure if that answered your question, I didn't fully understand it.

Really smart people are rarely pushed out of the industry. They just suffer. Usually people who say they were pushed are not that brilliant to start and are just making excuses

What are you basing that on? This is the worst in my experience in the games industry. So many people who strongly prefer to work indie instead of risk working with an endless cesspool of assholes.
