Dissident

is an 18th century English term
borrowed by Russians in the early 1960s
and soon exported
shortly after the Russian word
Samizdat (самиздат = self-publishing)
was sent around the world.

Dissidents in the USSR

showed that, there, in that post-Stalin circumstance,

"the pen is mightier than the sword".
Under the tyranny of consumer capitalism, however,

dissidents can be safely ignored.
