As other answers already indicate there is no such thing as a public opinion on people. Especially in the realms of internet comments there is a lot of binary opinions either adoring or condemning a public person. A good analysis of the reputation of people in the light of public opinion is way too complicated to be discussed here. However, I distinctly remember reading a lot of Orson Scott Card's reputation back when the Ender Game movie hit the cinemas. A lot of media outlets as well as the usual internet crowd focused a lot on his faith based views on homosexuality. [It even has its own Wikipedia section on his page.](https://en.wikipedia.org/wiki/Orson_Scott_Card#Views_about_homosexuality) I certainly don't want to take any stance on that issue here, but I read a lot about boycotts and general condemning of his stance on the issue and the societies he describes in his books - especially of the Ender series - in mainstream media outlets. Thus, have in mind that the public opinion about writers that are outspoken about (controversial) topics may very well be subject to heavy opposition in the web. On the internet the ones opposed to something are always louder and it does not necessarily have to do anything with the writers ability to write or give writing advice.
