Wikipedia absolutely can be propagandist. It's an incredibly attractive target for propagandists trying to insert their views and spins, and while the community generally manages to keep a rein on that for topic that get international attention, those which don't can be effectively captured by coordinated groups. To say nothing about the smaller international Wikipedias.

Wikipedia is extremely good at keeping and reinforcing a most popular point of view. Russians are using Wikipedia a lot, for example.
