Career
In 1996, Dempers became national coordinator for Breaking the Wall of Silence (BWS), a group which advocates for the rights of those detained by SWAPO during the Namibian War of Independence. Dempers was active with the Congress of Democrats. Dempers was a prominent anti-apartheid activist in southern Namibia prior to fleeing into exile in 1983 to join SWAPO. She and hundreds of other Namibian exiles were arrested by SWAPO in 1986 while living near Lubango, Angola.
She was tortured and held in the "dungeons" of Lubango prior to being released and repatriated to Namibia following the moves towards independence which culminated in March 1990.
Dempers became national coordinator for BWS in 1999, three years after its formation. She and other committee members were expelled by a faction of the party led by Ben Ulenga.
She joined up with the faction led by Ignatius Shixwameni and formed an "interim national committee".
