Historically speaking, it is very relevant. Because it clearly shows Hitler's intent for Germany, the war and the jews way before he got into power. Other than that, it is a crappy book, the content sucks and the writing is abysmally bad. The latter fact was also something people thought back then, and most people who had the book at home didn't necessarily read it.
Another reason the book is relevant, it clearly shows the power of propaganda and how books can be used to that end.

It's interesting from the perspective of historiography. But it's not relevant in the way the Bible, Quran or the Gita are.

This was my point. And in the context of TFA, it's not Lindy.

It wasn't an effective instrument for propaganda. The book became popular because of Hitler, not the other way round.
While the author was very influential, I'm not sure if the book itself relevant.
