The best way to change attitudes concerning governance is peaceful discussion. Try "soft" topics like past eugenics movements. These are soft because they are past events and few people are willing to virtue signal or fall on their sword for historical figures, especially obscure ones.
Sex sells. Talk about Dr Kinsey and his horrific studies. Show how his crimes were used to legitimize hedonism and destroy families. Hedonism is also a great distraction so it is yet another talking point.
After the pattern is demonstrated in a historical setting, the stage is set for discussing current sacred cows. Because you've already had enjoyable discussions and trust has been established, the information will flow with less resistance. Remember the enjoyable part. No one likes to be ridiculed or frightened.
