The Jewish perspective – as usual... – is twofold.
Love is at the center of many fundamental tenets of Judaism. Love of G‑d, love for one's fellow Jew, love of the Torah, and a general love for G‑d's creatures and His world. Yet just as G‑d has instructed that we love in great and abounding measure, He has also commanded that we hate.
G‑d created the world to comprise an equal balance of good and evil potential and power. There is no doubt that evil does exist today in its blackest form. Our job on this earth is to seek out the good and internalize it; and also to fight evil with all of our being. To fuel that struggle, we must hate the bad. In fact, that is one of the deepest signs of our love for good: just as one would hate a sickness threatening the life of their child.

Hate Hate Hate seems to destroy lives, I have seen it on the television on the news and so forth, so I understand hating wrong, I understand hating evil. Why is there so much hate over one's race and faith? How do you combat hate? It seems to be out of control to me, I don't think one can make a radical islamist see the light, they are so full of hate, and there are these people who are hell bent on having their way in US over the President, getting him out of office. They lost. But they're so full of hate, it's all they have. No hate makes sense, but I do understand hating evil. I down with that. I am trying to post anti-hate things in FB but I know no one rarely responds to them and it is so vital that people stop this mess, because it will only get worst, won't it? I hope that people can come together before Messiah comes. Hope. I would hate to see mass wars over stupidity. That's my thoughts.
Hate evil - that's the point here. Love the good and hate evil.
