Taken off Dictionary.com

Hate or hatred is an emotion of intense
revulsion, distaste, enmity, or antipathy for
a person, thing, or phenomenon; a desire to avoid, restrict, remove, or destroy
its object.
Hatred can be based on fear of its object,
justified or unjustified, or past negative consequences of dealing with that
object. Hatred is often described as the opposite of love or friendship; others
consider the opposite of love to be indifference. See love-hate
relationship.
Hatred is not necessarily irrational or unusual. It is
reasonable to hate people and organizations that threaten or inflict suffering
on oneself, or whose survival interests are directly opposed to one's own.
People hate impediments to their health and wellbeing. Popular objects of hate
include fascism, communism, nazism, war, slavery
and genocide. Often 'hate'
is used casually to describe things one merely dislikes, such as a particular
style of architecture, a demographic of people, a certain climate, a bad movie,
one's job, or some particular food.
"Hate" or "hatred" is also used to
describe feelings of prejudice or bigotry
against a group of people, such as racism, and intense
religious prejudice. Hate crimes are
crimes committed out of hatred in this sense. Sometimes people, when harmed by a
member of an ethnic or religious group, will come to hate that entire group.
This is not socially acceptable, as Western culture frowns on collective
punishment and insists that people be treated as individuals rather than members
of groups.
Hate is often a precursor to violence. Before a war, it is often
useful to train the populace to hate some nation or political regime. Hatred
remains a major motive behind armed conflicts such as war and terrorism. It is
not easy to know when hate is logical and when it has become counterproductive
and self-perpetuating.

Nothing interesting here caught my eye except the fact that 'hate is often a precursor to violence'. It's hard to differentiate between hate and dislike. It may seem the same to you but for me it means a lot. For me hate is a strong word which I will try to avoid labelling a person. Maybe dislike is more suitable to label some of the people I met along my life. When a person is disliked, I feel that he/ she is bound to change for the better that if he knows that he/she is hated.

Summary:
dislike - positive
hate - negative

Yaya I know that both words are negative in nature but what I'm trying to bring up is the degree of it. Why am I bringing all this up and probably wasting your time? Because it is bothering me right now and it may one day bother you. And preaching at the same time,

How can there be love when there's hatred
