Their sad meaning of mainstream

MAINSTREAM (n):

Do and say what the "leaders" want you to do and say, however irrational. People who do their own thinking are dangerous because they may end up not doing and saying things the "leaders" wish them to do and say. Indepedent thinking is potentially non-mainstream and should be curbed and regulated. Social integration requires people to behave and think in an automated way because independent thinking could lead them astray. These "leaders" do not believe social integration can be achieved through diversity of thinking. Diversity should only be in the colours of clothes you wear and the choice of music you listen to, and should not apply to any intellectual activity (intellectual sanctioning act?).

Welcome to the last century.
