If you're not open to criticism or are likely to have your feelings hurt if people don't immediately love your work, then this really isn't the way to go.
There's nothing quite as cringeworthy as a writer who replies to valid criticism with snarkiness. Sure, a writer won't necessarily agree with every comment that's made, but there's no reason to be an arse about it. The commenter has taken the time to offer their thoughts and suggestions on your work, and that's something to appreciate - even if it stings a little.
Sometimes, you just have to take it on the chin - or get out of the ring.
