 Reverting for no good reason 

So, after I took quite some time to improve an article that was in a poor state, you undid all my work with a click of a button, leaving only the summary ""rv - although currently unsourced, the content is technically correct"".  Clearly, you have no idea what constitutes encyclopaedic quality.  Clearly, you just thought it would be fun to piss someone off.  Did you find it immensely fun?  Did you laugh a lot to yourself at the thought of the time of mine that you'd wasted?  Did you chuckle for ages at the idiocy you forced into the article?  Let's just look at the first few changes I made, that you delighted yourself by undoing.

Self-arrest refers to various maneuvers employed in mountaineering
It doesn't ""refer"" to that; it is that.  You want to say ""Paris refers to the capital city of France"" or ""Nile refers to a river that flows into the Mediterranean""?
sliding down a snow or ice covered slope arrests (stops) the slide
 You think readers are too stupid to understand what ""arrests"" means in this context?
himself or herself
 You think the single word ""themselves"" is some how better expressed in three words?
and/or ice axe
 You never bothered to read WP:SLASH?
 These potentially life-saving techniques must be practiced frequently in order to maintain proficiency
 This website is called wikipedia, not wikimanual.  But you never bothered to read WP:NOT, did you?

That's five, I made many more, I left the article looking considerably better and more encyclopaedic, but then you came along and fucked it all back up again.  Do you feel proud?  186.9.130.34  
 No one cares how long you spent on writing you WP:OR, neither does it belong on Wikipedia. Your behaviour on this editor's talk page breaches WP:NPA, WP:CIVIL, and your edit summaries and general behavioural pattern are pure WP:BATTLEGROUND. If you persist in such behaviour, you will end up being blocked from editing. I am about to add a standard 'welcome' for IPs who think they know how Wikipedia works to your talk page, and trust that you will read our policies and guidelines carefully before you continue editing.   
Exactly what OR are you referring to?  186.9.130.34  "
