There is no Internet War on Creatives.
Yes, if you make something popular, you will get your share of haters. But unless you've made some serious mistakes, the haters will be far outweighed by the supporters.
It's easy to engage with the haters and hate back, but that just escalates the problem. If some says something negative, either ignore them or try to disarm them with a kind & humble response. You'd be surprised how often not retaliating and being kind can defuse an ugly situations. And if that doesn't work, definitely ignore them - no point in wasting your life worrying about someone who is being irrational and trying to offend you.
“He who takes offense when no offense is intended is a fool, and he who takes offense when offense is intended is a greater fool." - Brigham Young
It's easy to focus on the negative and ignore the positive. Don't. When someone takes time out to say something nice about you or your work, try to respond back, even if it's just a simple "Thank you." You should spend most of your community interaction time with your fans, not your detractors.
Seriously, just be nice. It's not always easy but it's easier than the alternative.
