Sadly, that doesn't mean much. Karin's got way too much Orochimaru in her.She is still better than Karin at least.
I've seen the hate mostly revolve around "she's useless", "a ****", and so on.karin has issues, but i guess that comes with the trauma of being Oro's experiment. Her and Sasuke will one day make babies and she will be crazy happy about it.
sakura is a great character in my opinion, shes well written for the romance aspect especially. some ppl probably do dislike her because thats their opinion, but 99.99999999999999% of the time its baseless, tasteless, useless hate. they think she is the only thing preventing hinanaru from happening, when thats quite wrong.
The personal opinions are there, whether they are shallow or baseless, but some of her fans have been a contribution to the their hate. However, they are not always the reason alone in their judgement of Sakura. But I do see your point ^-^ and it's very well distributed.People just don't know how to bash Sakura properly anymore...
When users say the hate Sakura because of her fans, only proves the lack of personality they have, if you let people to have influence in your judgement you are clearly dependent on what others think, and cannot develop a personal opinion, it's always influenced by others...
