Do you think staying in your silo and only listening to people you agree with is going to make that person go away.

I think that's part of it. But the other part involves a large heavily armed police/military given license to imprison, deport, and kill the people you want to ignore.

Staying in your silo while the Angels of Death expunges all the first born sons without lambs blood on their door frames is a way of divorcing yourself from culpability after you've endorsed the next Holocaust.
