wikipedia.plは安全ですか？

Polish wikipedia site uses a cenzorship, which is probably unavoidable to preserve reliability. Yet this cenzorship shows a clear tendency towards denying crime of communism and especially the communism and russian influences in contemporary Poland. This influence is the subject of an important debate in Poland, but wikipedia is hiding obvious facts and cannot be a considered a reliable source especially in this debate. An example is given here: ***** - administratory means are misused to prevent giving a fathers' name in a biography of a popular journalist. Possible cause is the fathers' involvement in the former regime. Yet I do not advice to omit polish wikipedia - it's unavoidable. I advice to use it with patience and help to develope it.
