I've worked with professional [0] critics.

They're constantly workshopping their bad opinions. And, if you try to straighten them out on a subject I can almost guarantee that your words and arguments, the ones that they'll dismiss or ridicule (usually verbosely) in the moment, are going to appear on the page under their byline. Typically expressed in tone that makes the reader feel lucky that they have decided to share their holy knowledge with mere mortals.

Is what you're talking about in their field? No? Well they're going to use the same tone and rhetorical tactics to talk about the things they know nothing about.

Demonstrate that they're wrong in a way that's not useful to them? Well, you've just made an enemy for life. Hope you like receiving 9,000 word emails that could have been boiled down to "How dare you tell me that I'm not perfect?" Why use 9 words when you can use 9,000? Not getting the point? No worries, they'll tag in three of their friends.

As a class, they were poorly paid people, personal lives in tatters, with little knowledge or experience of the world, all crawling over eachother to be see as the "thought leader". The one who gets to tell everyone how the world is to be run.

To be famous.

The kind of people who, if you were stuck on a snowy mountain, would burn down the shelter you're building (too slowly in their opinion), complain that it's too hot, and the when the fire goes out, attack you for letting it get so cold. "What happened to that shelter you were building? It burned down? Well, how could you let that happen?"

Don't even get me started on the lies and excuses (never. ending.) While still maintaining a public reputation for "honesty and transparency". It doesn't matter if it's true as long as you keep saying it.

Ended up getting lawyers involved and maneuvered them into putting every stupid thing that they did in writing before walking away. They're still doing the same kind of stuff at about the same level that were doing it 10-12 years ago. Self-limiting. It's not even worth attacking them publicly, there's nothing that I could do to them that they aren't already doing to themselves.

Learned a few things from the experience:

-1: If you have something to communicate, communicate it yourself. Never allow anyone communicate an important message for you unless you’re standing right behind them.

0. Don't try to help people if you need help yourself.

1. Work with people who want to be known for what they do, rather than what they say.

2. Selfishness and myopia have no floor. You can set the bar for success as low as possible and some people will still find a way to blame you when they trip over it.

3. End quickly. If someone acts in bad faith even once, it's over.

[0]: Professional meaning that someone, somewhere, paid them something for their opinion. Not to be confused with professional conduct.
