You've made three mistakes:
 
Is the version I'd reverted to - unstable? On the contrary: the version that you were attempting to revert to - is unstable, because the chapter you'd removed, was added three years ago (on 5 May 2008), and lasted until 14 March 2011, i.e. until the day before yestreday, whereas the version you were attempting to revert to - lasted for less than 40 hours only - that were uncontinuous and broken, so which version is more stable?
Returning the chapter you'd removed - is not against the consensus at all. The chapter is supported by User:(MOB)DeadMeat, and is also supported by User:Chrishatch1973, and is also supported by User:Eliko; whereas the removal of the chapter is supported by User:Basket of Puppies only. Really, it was also supported (in the past) by User:DragonflySixtyseven, however their reason for the removal - was refuted on their talk page (and on the article talk page as well), and they didn't respond to the refutation. According to the law: Silence gives consent, the very fact that User:DragonflySixtyseven didn't respond to the refutation - shows that User:DragonflySixtyseven does not reject the explanation given on their talk page (and on the article talk page as well) for returning the chapter. To sum up, three editors (User:(MOB)DeadMeat, User:Chrishatch1973 and User:Eliko) support the chapter, and one single user (User:Basket of Puppies) rejects it, so which option is more consensual? Returning the chapter, or removing it?
The chapter you removed is relevant, as I'd explained on the article talk page - before you removed the chapter. If you think the chapter is irrelevant - despite my explanation (on the article talk page) why it's relevant, then please discuss that on the article talk page.

Note that when you responded to me on my talk page - each one of us had made one revert only - during 2011, so: considering that the single revert I've made during 2011 - was sufficient for you to warn me of your reporting me for WP:3RR and edit-warring - if I "continue to revert", also your single revert you've made during 2011 - should be sufficient for me to warn you of my reporting you for WP:3RR and edit-warring - if you "continue to revert".
If you continue to both - remove a consensual chapter - and replace it by an unstable version which is against the consensus, then I will report you for violating Wikipedia policy, that requires - to discuss everything on the article talk page - before removing a consensual chapter and before replacing it by an unstable version which is against the consensus.
Anyways: due to your claim about irrelevance, I will add to the (stable consensual) chapter - some clarifications, to make sure that every reader (including User:Basket of Puppies) understands its relevance.
