From 1979 on, Viačorka has been an active member of the national-democratic movement in Belarus. He was one of the founders of several juvenile cultural groups and organisations, such as Majstroŭnia (Майстроўня, 1979–1984), Tałaka (Талака, 1986–1989), and the Confederation of Belarusian Juvenile Organisations (Канфэдэрацыя беларускіх моладзевых суполак, 1988–1989).

In 1988, he was one of the founders of the Belarusian National Front. Viačorka was head of programme documents commission and a member of the party’s central board. In 1995-1999 he was deputy head of the BNF.

Vincuk Viačorka speaks several European languages, is married, has two daughters and a son. His wife Aryna is a mathematician. His son Franak is a youth activist for the BNF, and is a former student of the Belarusian Humanities Lyceum. Both Vincuk and his son were featured in the 2006 documentary film by Mirosław Dembiński, A Lesson of Belarusian.

In 2016 Vincuk Viačorka publishes the book “In Belarusian With Vincuk Viačorka”. This is a series of essays based on the eponymous Radio Liberty internet page program. Viačorka encourages his audiences to dissect the rules and principles of authentic Belarusian, a tongue which suffered serious distortion in the wake of Communist mandates on “language merger.” Vocabulary and onomastics, grammar and pronunciation, spelling and syntax are all covered in concise, easy to read lessons. Viačorka gives long overdue attention to a distinct and vibrant language which is an indivisible component of the modern European linguo-cultural space.
