Why do we hate each other so much?--an epidemic of anger

[Robban]

What is hate?

Is it a form of partiality?

Or is it caused by partiality?

This one but not that one.

Like making a choice and we make many choices each day.

Excluding and including, well, we did eat from the forbidden fruit after all.

Why was the second Holy Temple
destroyed?
Because there was baseless hatred between them.
(Talmud Yoma 9b).

David says in Psalms 139:21-22,

"Indeed I hate those who hate You, Lord; I contend with those who rise up against You."

"I hate them with the utmost hatred;
I regard them as my own enemies."

I think David was referring to the wicked who use the name of the
Lord as a cover for evil schemes.
