Curate, connect, and discover
Take criticism like an adult. You won't always hear what you what to, the writing that you put so much time and effort into may be torn apart, but you have to roll with it. There's always some truth to complaints, some people just love tearing writing apart, most are honestly trying to give you feed back. If you get mad or cry how will you handle the publishing process? Most people get told no many times over, it's life.
So, don't be rude or outright ignore it. Take it to heart and if you get a complaint more than once it probably does need to be changed or fixed. If you handle this with a good attitude and act respectful, people will be less likely to rudely rip your stories apart. Besides, the compliments are worth it in the end.
