Great post and I agree that there are lots and lots and lots of folks that put their heart and soul into a production.
However, I believe the solution here is not to look to others and say 'don't say this don't say that.' People will say what they want. That's life. The solution here is simply to look to ourselves, and not take anything personally. Period. Not just with this board. But with life in general. If you don't take opinions and what is said personally, it will not affect you in any.way.
So let others bully if they want to bully. Let others be negative if they want to be negative. At the end of the day, "the energy you put out into the universe will multiply when it returns to you."
Continue putting your heart and soul into your work and leave it at that. Do not take anything personally. Many people will lightly say they don't, but that's questionable. We take everything personally as human beings. It's a natural reaction. It's all about us, or at least we want it to be. But in reality, what others say about you or your show is none of your business. Your business is to do the best you can and everything else is out of your control.
Again, I can't say this enough. Don't. take. anything. personally.
Just a peace of my mind.
