Domestic Terrorism or Terrorism Anywhere
It's SELF-IMPOSED IGNORANCE
Where one group opposes another group based on myths, mis-information, implied or intended in order to have their own way, "tom-foolery".
Bigotry is the foundation of Racism. And racism is an "action" against a group of human beings to prevent or deny them from enjoying their civil liberties, such as voting, employment, or the same respect racist and bigoted individuals desire for themselves, "Do unto others as you wish them to do unto you."
Self-imposed ignorance is when one has grounded themselves so deeply in mis-information, fear, hate, and their own belief, they are superior to others in all human endeavors. Such a sad state of negativity to live in.
Of course such myopic concepts are not supported by historical truths of all cultures and ethnicities around the world. (We all stand on the shoulders of others who created, invented or provided a better path to follow.) Thus, attitudes of human superiority above other human beings, suggest an arrogance of what Humanity really is.
Blinded by egotism including a Selfish Mindset mirroring that of small children screaming, " it's all mine - give me that - I want it, it's mine."
Wars start this way as well, domestic or International. But, Life itself demands a Responsible adulthood put away selfish childhood ideas, does it not?
Bigotry of all sorts is poisonous to the progression of human life on this planet. Thus, actions to deny that progress with activities of Racism, indicates an addiction to Bigotry on steroids.
It would seem those in leadership, including all parents would desire to promote truth to our youth, instead of fear, hate, and prejudices that signals only "my kind" matter. (Coded racism destroys creativity in children)
