Because I don't care? If it bothers you then fair enough. But why should I be bothered by something I don't care about just to satisfy you?
Because that is part of the forum rules.
I found the book entertaining. Its factualness is completely irrelevant to that. Not sure how the fact you're a professional aerospace engineer has anything to do with what books or categories I chose to like or believe in.
You asked for recommendations for "good" books. You got lots of lovely answers. Why come on a forum like this if you are not willing to engage with people? You are talking about an area of professional expertise of several members here and completely pooh-poohing it -
that is why it matters. I find your assertion that you thought this forum was for hoax believers a bit odd - why would anyone join a forum and start posting without having a look around first?
A number of horror films claim to be 'based on fact'. Do you walk out of the movie the moment that pops up moaning to others that it couldn't possibly be true and they are all sockpuppets to the director?
Apart from the fact that Jason does not like horror films... such films do not often besmirch the reputation of (thousands of) people living and dead, several of whom are on this forum or well known to the people on it. When it does happen, the film-makers are roundly criticised.
Furthermore, we are talking about very basic fact. If you saw a film which proported to be factual but had Napoleon being Italian, would you not pick that hole in it? Indeed, there are miriad internet fora and books which are based around picking up such errors. The basic errors in the book we are discussing here are an order of magnitude greater than my Napoleon example, yet the author expects it to be taken seriously as an entirely non-fictional work (unlike horror films).
Interestingly, as an aside, the book does not appear able to be purchased anywhere online, so I am very curious as to where you got it from if you are not the author himself.
