I'll be defining these terms with the Merriam-Webster Dictionary.
ANGER FIRST;
verb: a strong feeling of being upset or annoyed because of something wrong or bad : the feeling that makes someone want to hurt other people, to shout, etc.
Anger according to the definition above is "a strong feeling" of being upset because of something wrong or bad. It could be towards self or another person, but the source of anger mostly arises from a strong feeling of hatred for a particular thing, could be an object, someone else, yourself or a pet, which leads to the second word;
HATE;
verb
: to dislike (someone) very strongly
: to feel hate for (someone)
: to dislike (something) very strongly : to find (something) very unpleasant
noun
: a very strong feeling of dislike
Hate is also defined as "a very strong feeling of dislike" (this time with very), and this particular feeling could also be at someone or something. The consequence of HATRED and ANGER is mostly FEAR.
FEAR
noun
: an unpleasant emotion caused by being aware of danger : a feeling of being afraid
Fear is a "feeling of being afraid", afraid of someone angry at you, afraid of the quantity of hate speech you'll get today, everything that causes one to fear is that strong feeling of hate or anger.
The most exciting message a piece could pass to me about fear, anger and hate was gotten from a series, "13 reasons why", the piece goes thus;
Hate, anger, fear. Those are lies they use to turn you against each other. When you set aside the hate, they force you to carry, that's when you know, love is our true nature.
The piece absolutely defines the untold truth behind HATE , FEAR AND ANGER. They are shenanigans to cloud love, they are the obstruction to peace and personal Inter-relationships, they are the lies packaged in a box full of gold, they are the wolves in sheep's skin, if only we can see through hate and find at the bottom obsessions which should be transfered into love then not only Nigeria but the world would be filled with love and know that Love is our true nature.
