At least in case of the Nazis it was not so effective. The Nazis did not come to power by propaganda. In elections they did not exceed about 1/3 of the votes. The got to power by having another party voting the power to them. Afterwards they actually used plain old violence and economics to achieve their objectives (i.e. it paid to "come along").

Interesting to add that Hitler specifically used "cancel culture" techniques copied from the communist party in Germany at the time to dispatch those who were standing in the way of winning that power. Making the decision to "come along" the default. (Shirer, 1960)
