I think that with the overwhelming majority of media sources supporting (or not caring about) Tim's leanings, it's only articles like this that give anything like a mainstream voice to the 'haters'.
The fact is, whatever and whoever a person is, whatever they do and however they identify themselves, someone will tweet/post/rant against it somewhere. Tim is no different, except it's to do with a person's sexuality --- something society loves to talk about.
Imagine the furore if he was seen using an Android phone.
