Okay, so ignoring everything that happened on previous pages, one tip I can give is to think the comments through and see what the readers think, but do not try to fix what they point out. Find what's the guy's problem, find what's the cause of the problem, and think what should you do about before actually doing anything.
As other people said, while some constructive criticism is always welcome and you should reflect on it, there will always be that one jerk complaining because of something completely stupid. I once had a guy giving me one star review and complaining about trans stuff and lack of other stuff (straight characters, for example) in a story about a trans girl. This got me upset for a while, but hey, he was right in the end about the fact there were no straight characters in my story. Basically, he wascompletely right, but the way he worded it was awful.
So my advice is to just analyze the comment. Some of them might hurt at first, but even if someone wants to burn you on a stake, there is no smoke without fire and that complaint definitely comes from somewhere. When you find the reason for the complaint, you think why and how you wrote that particular part of the story, and think what you can do about and if you should do anything. When you're done with it, the guy might be complaining still, but it's your story and you know the reason for the complaint, so there's nothing to say you wouldn't already know and decided it's alright.
