Having watched gold closely for the last two years I disgaree. In my observation, technicals have routinely been the driving force behind the major moves on gold. The other major moves typically come ahead of and after FOMC meetings, relevant geo-strategic events, etc.

It is certainly a manipulated market in the sense that the purchase or sale of up to 10,000 future contracts all at once is not exactly a rare occurrence... but it's rare that there is an irrational, major move on price.
