Well now, lets analyze this. The country has a president that is black.
Maybe the people refusing to take the pledge, just do not like black
people, fearing that maybe blacks are too stupid to lead the country.
So, don't take the pledge if the country is ran by a black person.
On the other hand, some people don't want to take the pledge because
if Hillary is elected, they just could not support the communist and
pledge allegiance to her.
Then again maybe, some people feel like supporting the flag is supporting
some piece of shit like Obama, who wants America to lose in Iraq, and
anywhere else, who wants America to destroy all it's nuclear weapons,
to show how peaceful we are.
Then there are those who support the Constitution. All servicemen
take an oath to support the constitution from all enemies foreign and
domestic. Maybe supporting the constitution means you can't pledge
allegiance to America if it is led by communists.
It is a are deep question that you may not recognize at first.
