Wikipedia, the free encyclopedia:
dissident, broadly defined, is a person who actively challenges an
established doctrine, policy, or institution. In a religious context,
the word has been used since 18th century, and in the political sense
since 1940, coinciding with the rise of totalitarian systems,
especially the Soviet Union.
In memory of Alexander Solomonovich Pinsker (1937 -2017) who was forced
to leave Soviet Union for political reasons in 1974.
