I view people putting their bullying opinions out there like a flasher in the park. They run up, show you stuff that is none of your business to be seeing, for the purpose of making you feel uncomfortable. So, in my opinion, overt your eyes. Don’t be a voyeur to internet exhibitionism. They are trying to violate your boundaries.
With all that said, here’s what I think should be happening in a writer’s group, and here is what I tend to do when I put up something for review:
1- I bring a pen and paper.
2- I shut up!
3- I listen.
