edit: oh, one starts to write a comment, attends the phone, and your idea is already submitted :/.
For one, fiction is not evidence. Using it as such is poor reasoning.
For another, I've seen a reaction of "that's just fiction, it wouldn't actually happen" distracting from the important points.
Note that I didn't say that I think the book is harmful, but the focus on it.
But this is not always the case - for the younger generations who are not familiar with the issue, 1984 is a very important piece of literature. For those of us who have suffered decades of ignominy over the crimes of our governments, sure: fatigue is the issue. But, we must never be willing to put our freedoms aside, for a little relief from repression. Always be aware, and always fight back!
So yes, reading 1984 is beneficial. Only reading 1984 is not.
"Only reading 1984 is not" helpful? I definitely do not agree. Reading at least one of these works at least provides the opportunity to consider its relevance. Reading none of them trivially throws out that potential benefit.
You can also consider Chesterton's The Man who Would Be Thursday, referenced in that review as well.
