When I first started sharing my writing, I was scared that people would be rude to me because I was learning how to write novels and since English is my second language and I had just recently become fluent, I was scared of making so many mistakes.
The only reason I got over that fear was because I finally accepted that not everyone was going to like the way I write. It didn't matter how many beta readers I cooperated with, how much constructive criticism I got--- there was always going to be one person dissatisfied with my writing.
Trolling/hate comments are something else, I don't pay attention to it at all because well, it's trolls. They're people who have nothing better to do, are jealous, or they're miserable overall. Granted, it's not something that should be tolerated because the comment section of a comic/novel should be to enjoy the work with other readers, so I think it's fair when authors report/filter those comments.
I honestly appreciate all kinds of feedback/criticism when it comes to my writing because it helps me a lot with things that I'm completely oblivious to, unless it's done in a sh*tty fashion.
