If you go along with government hoaxes like 911, Sandy Hook, or Paris Attacks, the message to the government is either you really are duped or you feel coerced into upholding their hoaxes. Either way, you lose.
If the sophisticated antigovernment forces on immigration are duped by hoaxes, then the government concludes it can hoax everyone else to vote for them at election time. Or not to contest the stealing of elections by vote counting fraud machines.
If the antigovernment forces are coerced into pretending to believe in hoaxes they know are hoaxes, then it shows government it can intimidate even the most maverick opposition. That means the government can intimidate everyone else and rule by hoax.
Either way, with hoax you lose. The government knows that too. They laugh at you with contempt when you use their hoaxes to try to limit immigration or the spread of Blacks into White communities.
