You can take it for a given fact: 
Somebody on this earth is not going to like everything you write either, and they will go to great pains to tell the whole world about it.  When they curl their lips back and say, "DUH" they have done told everything they know about the subject. 

Learn to live with it.  And don't ever try to educate people like this, when"DUH" is 97.2% of their vocabulary, you will NEVER convince them that the sun rises in the east on Tuesdays even if you should labor all the days of your life.

That is one of the lumps in the pudden.

I don't care what kind of writing you do, the more public attention you receive, the faster and heavier the criticism you will find is showered upon you, your work, your stance, and your precepts.

Here is my policy for dealing with critics..

1. If they are just cussing and fussing, hollering from the bushes with obscure denunciations among their so-called friends, gently ignore them. I say "gently" because even a half wit will be listened to by people too lazy to think for themselves, thus making one harping fool a worse enemy to have than all the close-lipped Solomons on earth combined.
2. If their comments are specific enough to evaluate; study their remarks and thank them even for their stinging ridicule, especially if you realize they are right.   All too well do I remember one secretary saying she could write an article better than I had turned in.  I looked at her writing, and she was right.  She could.
3. If what they say actually helps, pat them on the back, and ask for more as soon as you can take it.
4. Remember my epigram: The only thing worse than being criticized is finding out nobody cared enough to correct me.
    

You've seen those signs on back of trucks saying:  "Tell me how I'm driving."  That's the sign of a very insecure driver, constantly needing reassurance from everyone on the road that they are doing things at least halfway right.

Don't ever depend on non professionals to evaluate how well your stories drive. 

In fact, if you believe in your work with all your heart, don't let ANYone's good or bad evaluation deter you from that belief. 

On the other hand, If you need help and know it, don't be afraid to ask.

I constantly hear the advice to QUIT rewriting your work when you have invested all the time in it that you can afford.  That is like producing a half-baked potato.  Do that consistently and chances are you will end up working for editors so far down the food chain they have to like it or lump it.

The advice to quit when the bell rings may be true for the polished writer, but the only way I have found to become a polished writer is to keep on rewriting anything you produce until you are a polished writer.  Even after you are selling much of what you write, my experience says to come back to rewrite what you have already sold until you are proud of it. 

In order to become a great writer
strive for greatness in all that you write.
Writers get better with age 
only if they push themselves to get better as they age. 

You can write quicker, faster, and better by drilling yourself to get better at spotting what needs rewriting, before you put it down on paper.  Soon the words you write in the first draft will be truer to your higher self than the words you produced only after the many rewrites you did in the beginning of your career.
