Language And Identity Book

I wanted to give this book a 5/5, because I learned so much. It is scientific but still relatively easy to read, not overfilled with scientific data and terminology. A lot of language philosophy, nation building, some history, social identity... And then I reached the last chapter (the one about Lebanon - or not?) and I started to hate it. That chapter also starts off very well, really informative, but then it looks like the author got drunk or something, it takes such a detour of its original topic, there are 2 subchapters about some dude which don't have almost anything to do with the proposed theme of the chapter as suggested by the chapter title and it is just... Way, way, way too long. And then, compared to that, the closing 1-2 pages of the chapter are very sudden, short and weird. There was a time where I didn't know what I was reading.
I can only forgive that weird side-tracked babbling (kind of looks like the dude really wanted to prove a point he has been thinking about for years but never had the right medium/book for it and now could finally do it, even if it is not fitting, and I restate, disproportionately long) because the rest of the book is great.
