Before Engaging Brain Check That You Are Permitted

SEE HERE  Exactly where in the Constitution is the government given the power to tell people what and how to think?  Did I miss that clause?  This is so outrageous it goes beyond anything one could imagine.  Check your brain at the door when you join the Air Force, right?  People have fundamental rights and that includes reading what they damn well want to read.  The fact that the government is engaged in over reach and that the president is a despicable power hungry narcissist can not have been missed by anyone except those whose brains have been turned off due to neural depletion and excessive liberal propaganda.  Can we get some sanity back before the whole thing implodes?
