The problem with what it says in the Bible is that it is unconditional one way or the other. All love and no hate. However all of these things are conditional. Even in the case of hating someone: the emotion of hatred is natural and should be expressed so that justice is obtained. Subduing your attacker with physical force, but sparing his life so that he can learn from his mistakes is an example of this.
This same applies to Jews, where one first needs to hate them and cannot forgive them until they are subdued. If unconditional love was applied, the Gates would go unchecked, and so on.
The problem with Jews is that their souls are not similar to Gentiles. Jews are parasitic souls designed to look human to subvert the Gentiles. This was admitted by top Rabbis. See the web article and video below:
This is why Satan is opposed to them. It is because they are almost the opposite of Gentile souls and are our soul enemies. They are parasitic whereas we are self sufficient. They want to sacrifice animals and nature, whereas we hold animals sacred. They want communism and hive mind, whereas we want independence and liberty.
Also, what you mention about removing hatred for other Gentile souls: Through spiritual advancement, humans have the ability to fix their souls and trauma that occurred to them. Nobody is doomed to be criminal or stupid or whatever forever. In this manner, nobody has to be put to death if they are willing to meditate and fix their souls.
As a real example of this, you can see people in this thread working on freeing their soul from past issues:
In this manner, everyone is accepted because everyone can be fixed with enough time and energy.
