That's too bad. The religion encourages it's members to "be no part of the world". They can associate with "worldly" people, but only with work or sometimes with unbelieving relatives, but are encouraged to not associate with "worldy" friends.
It is not our religion that encourages us to "be no part of the world", but Jesus through the Bible at John 17:16. This does not mean people exactly, Jehovah's Witnesses love everyone, that is one of the reasons why we go from door to door. There are several ways of being "no part of the world" all of them being taken from Jesus Christ's example. JW's do not get involved in political affairs of the world, we remain neutral. When Jesus was questioned by the Roman governor Pontius Pilate, he stated: “My kingdom is no part of this world.” In response to a question as to Jesus’ role, he told the governor: “For this I have been born, and for this I have come into the world, that I should bear witness to the truth.” (John 18:36,*37) When the Devil offered him all the kingdoms of the world and their glory, he refused. When the people wanted to make him king, he withdrew. (Matt. 4:8-10; John 6:15) Jehovah's Witnesses do not sidestep the fact that Jesus referred to the Devil as “the ruler of the world” and said that the Devil ‘had no hold on him.’ (John 14:30) They could see that Jesus did not seek involvement for himself or his followers in Rome’s political system but that he was fully occupied with declaring “the good news of the kingdom of God.”—Luke 4:43. We also shun the spirit of the world—its aims, ambitions, and hopes, as well as its selfish ways as brought out at John 2:15-17.
So please don't think we are shunning people when we say we are "no part of the world". We work shoulder to shoulder with people that are not JW's. Our children go to school with other children who are not JW's. In connection with avoiding the badness of the world and associating with God’s people, the apostle Paul wrote: “Do not become unevenly yoked with unbelievers. For what partnership do righteousness and lawlessness have? Or what fellowship does light have with darkness? .*.*. Or what portion does a faithful person have with an unbeliever? .*.*. For we are the temple of the living God; just as God said: ‘I shall reside among them and walk among them, and I shall be their God, and they will be my people.’ ‘“Therefore get out from among them, and separate yourselves,” says Jehovah, “and quit touching the unclean thing,’” ‘“and I will take you in.’” ‘“And I shall be a father to you, and you will be sons and daughters to me,” says Jehovah the Almighty.’” Notice the repeated advice about avoiding wrong association, ‘from these turn away,’ ‘get out from among them,’ ‘separate yourselves,’ and then ‘I will take you in.’ There is to be no partnership, no fellowship, no portion, no sharing with unbelievers. In other words, no association with them if one is to associate with God.—2*Cor. 6:14-18; Ezek. 37:27, RS; Isa. 52:11; Ezek. 20:41, RS. Paul warned Christians against associating with those who had no hope in a resurrection and hence no real incentive to right conduct. “Do not be misled. Bad associations spoil useful habits. Wake up to soberness in a righteous way and do not practice sin, for some are without knowledge of God.” (1*Cor. 15:33, 34)
