Only a European could conceive of this document as "Right Wing," if by that you mean "Liberal" in the 19th century sense of the word. I think it is seen this way by the more socialist countries. Many in the UK, for example, see it as too "left wing."
Freeper tend to see it as enshrining in law socialism and the centrality of the State. The "liberalizations" seem token and trivial to right thinking Americans. Only the core leftist of the Democrat Party in the USA would vote for this monster.
