Here's an advice to all the writers; prepared to be critique or don't be a writer at all. Go lives in your fantasy where harsh and rude comments don't exist. Don't write a controversial story if you don't want to be critique. 

 People will comment on your book based on how they feel about your book. If your story is good then many people will like them, if not then they will insult them. 

Don't be over sensitive and blamed the readers lol.

I maybe downright rude but there's no different if I express my opinion or keep them to myself because it doesn't change how I feel and think and Idc how you feel and think about me.
