Are “right-wing progressive” or “left-wing conservative” contradictory terms?

[Beet]

Typically you see this in communist countries. For example, Chen Yun, Li Peng and Leonid Brezhnev were left-wing conservatives, while Gorbachev, Zhao Ziyang, and the like were right-wing progressives, although more accurately called reformers. The typical LGBT supporting western style liberal in China today could also be called a right-wing progressive, since their views are identical to western progressives, but they are positionally right wing within their own polity.
