You will soon see many comments "misteriously" disappear without leaving traces, especially the ones telling the truth about US, "democratic values", "rule of law" and their similars. The better the comment, the faster it "evaporates". As such comments do in Russia or China related discussions, whatever the exact mechanism is.

This forum is not for you to get information about the american "public opinion". It is rather used to shape it (as a myriad of other similar forums in the "free world").
