Always forgive your enemies.
Nothing annoys them so much
- Oscar Wilde

Jews are taught, "Love your friend as yourself." The word "Re'echa" does not have an equivalent form in English. It is certainly not a friend or neighbor. Furthermore, the concept does not necessarily mean that everybody should love everybody else. It only refers to those who share your objectives and ideals. That means that in some cases you do not have the need or the obligation to love another person.

If another person does not share your ideals, it is difficult to enter into a dialogue.

However, this may not represent a serious problem. You may not want to enter into a dialogue with people whose goals or ideals conflict with yours. You may not want to be influenced by their points of view. This is thoroughly acceptable.

However, if a person actively hates you, then it may well be impossible to to enter into a dialogue.

There is a third option as well.

You may have a problem dealing with your fellow Jews who present ideas that differ from yours, yet they are consistent with your own goals and religion. You cannot hate such a person. You should accept that person even though you differ with some concepts.

You have no justification for hating the person, despite some wrong or improper actions. To the contrary, the Jewish religion limits the circumstances under which it is permitted to approach and reproach such individuals.
