I think it's a good thing to be able to say ' I don't know enough to comment' and conversations would be much more healthy if we could say this more often.
However calling the laptop scandal a bullshit conspiracy probably means you don't know enough to comment on that either.
I wasn't scolding anyone about reading a book, I was responding to a user who literally said 'I have read everything about it ages ago' - a clearly ludicrous statement, so asked them if they had read that book.
