So this could be a two part discussion:
We are often told in America that other countries like Russia and China use propaganda to control the public opinion of their country. Would it not be completely reasonable to say the same happens in America?
Then to follow up:
What opinions are we lead to believe in this country? I’ve seen a lot of gay rights issues and stories that we have nothing to fear from Islam. Could these be narratives that we may not wholly believe, but go with the flow so we’re not publicly shamed? What could be the purpose of this propaganda?
