I've been tossed out of three critique groups. I even had one author throw a handful of pens at me.
Am I the critic from hell? Maybe. What I've found in these groups is 1) they want praise instead of pointers; 2) they are using the group as a therapy session; 3) they have no serious intention of publishing. I also found critique groups were an incredible waste of my time.
I also scratch my head at the notion that a group of unpublished writers are listening to the advice of other unpublished writers. A great example of the blind leading the blind. Going in with a few books under my belt didn't work in my favor as I was written off as a fluke. The one-in-a-million instead of an example that publishing is possible for anyone.
I've come to realize that many people love the idea of being a writer more than actually writing. There seems to be a perception of the writing life that has absolutely nothing to do with reality. That's probably Hemingway's fault. I also love people who blithely say "Oh, I should write a book! I've had an interesting life." People, it's not as easy as it looks.
What nobody wants to hear is that writing is more than throwing down words on paper. There's actually craft to the process. Also punctuation, grammar, POV, voice, story arc and even rules. When new writers realize how much there is to learn, the process loses some of its glamour. Now it's just WORK. At that point they seem to go in one of three directions: denial, depression or determination.
The first allows the writer to tell the group they're wrong. Why? Because this person received "A's" in English. Plus, their mother and all their friends just love their writing. An agent will see what a unique voice they have and wil clean up the manuscript and publish the book to great acclaim.
The second gives the writer permission to give up the dream of writing. Criticism just proves the writer was never born with talent so why try? Better to lick the wounds and grieve for a career that never was.
The third writer suits up and says, "Okay, show me what I have to learn." This writer takes on the job of writing but in the process discovers much more than they ever learned in school. They learn introspection and dissection, they understand that ego has no place. It can be brutal and infinitely rewarding.
There are only two people allowed to read and critique my work: me and my publisher. If it pleases both of us, it's ready for human consumption. Writing is not a demographic process and no writer should wait for others to decide when the manuscript meets their standards. Only one name is going to be on the book, only one person will get credit or blame.
