Censorship On Youtube Rankles

SerpentZA published Jack of all Trades, China has None!* on Youtube.com, so I made an observation as to why that might be the case, based on China's history and demographics. My comment was promptly removed. Why, and by whom? By SerpentZA, or by China, or are they one and the same? Just curious, I suppose, but any censorship rankles. The truth wants to be read.
