Love has its day. A thin line separates love and hate. Boy and girl hate each other. Boy and girl fall in love. Boy and girl live happily ever after.
Human natures makes it easier to hate than to love.
Hatred can take on national proportions. An example of this collective hatred is the obsessive Clinton-haters that have been venting their spleens for the last decade. I thought when Clinton left office, the Clinton-haters would go away. That is a small price to pay for having another Bush in the White House. Finally, the USA would again be one nation, undivided by haters of Bill Clinton.
