The propaganda models of Goebbels, Hitler, Stalin, Mao, Castro, et. al. have been refined and honed to a sharp edge in 21st century America.
The elite would have you believe that "there is strength in diversity". Therefore, even if we have to force diversity down your throat, it will make you stronger. Really? Common sense and observational skills would tell you that forced diversity creates division, distrust, and eventually weakness.
So how did people accept this nonsense and all the vehicles that deliver it like the quota system of "affirmative action", forced school bussing, forcing communities to accept subsidized housing, putting local police under federal control and on and on? The elite achieved acceptance of these odious means through a constant drumbeat of propaganda. The society has been subjected to a giant psyops regarding diversity, and it has worked.
Similarly we are now witness to the final psyops. If Hillary is elected it will be the final nail in the republic's coffin.
As to your second point, Diversity is our Demise.
The majority - by a large margin - do not trust or actively hate the msm.
We do care.
