The issue with this thought process is that its not possible to silo a shame culture around just the things you think should be shamed. Once you accept that the government encourages shaming people for things you think people should be shamed for you need to accept that other people have the power to get the government to shame you for things you dont think you should be shamed for too. For example in the US if the GOP came into power and shame policy was seen as acceptable theyd immediately institute a shame policy around abortions. Suddenly youre in a full blown thought police society
