You have a right to your opinion. If you happen to read something written by me and don't like it, that's your right. I know and understand that not everyone will be a fan, I do, and it doesn't bother me.
At all.
If I cared about and took it personally about people not liking what I write, I'd be sad and probably depressed.
You are allowed to like and dislike things. You are allowed to be honest about what you think of something. I don't take offense to as much as you think I would. As long as you're not blatantly being disrespectful, or rude, I'm good.
Providing Criticism is the best way to help a writer get better at their craft. How can someone expect to get better if no one is willing to be respectfully honest? So, please, don't assume I'm going to bite your head off because you don't like something I wrote or you found mistakes or contradictory statements and want to point them out to me. I SWEAR I'm not going to go on a rage-ling rampage. You have my word.
Have you stopped writing?
