I think there are two kinds of love.
1. The openly showed love to our brothers and 2. the love that wishes the enemy to repent and to come on the good way back (If he did not something unforgivable).
I believe the showed love belongs only to our brothers.
Brothers are Christians and Jews.
Christians in Jesus and Jews in the faith of Abraham, Isaak and Jakob.
Paulus wrote about the order of the church-community.
There he says that if somebody is really evil, we are not allowed to associate with him. We are forbidden to meet him, eat with him, invite him etc.
So I think we Christians have to see the Gospels in the light of the letters of Paulus and in the light of the "Apostles Story" of Luke.
Muzzies, Nazis and Socialists are no part of the showed love at least they repent totally.
We Christians are clearly not allowed to associate with them We have to avoid them.
I have found a chapter about this issue. It deals with immoral behaviour. If Paulus is here so strict, how more he would be on a Muzzie:

1.Korinther 5 (KJV) Kapitel
1 It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife. 2 And ye are puffed up, and have not rather mourned, that he that hath done this deed might be taken away from among you. 3 For I verily, as absent in body, but present in spirit, have judged already, as though I were present, concerning him that hath so done this deed, 4 In the name of our Lord Jesus Christ, when ye are gathered together, and my spirit, with the power of our Lord Jesus Christ, 5 To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus. 6 Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump? 7 Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us: 8 Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth. 9 I wrote unto you in an epistle not to company with fornicators: 10 Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. 11 But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat. 12 For what have I to do to judge them also that are without? do not ye judge them that are within? 13 But them that are without God judgeth. Therefore put away from among yourselves that wicked person.

In addition to that I know some Christs, who doesn't shake hands with evil people. I.e. Closed Brethren Community (followers of Darby).
