No doubt, they have toned down the language over the years
Consider a recent study article (25 Oct 2015):
4 The Scriptures counsel those who want to do God’s will not to love this world and its practices. (Read 1 John 2:15, 16.) The religious, political, and commercial elements of this world—including their information channels—are under the influence of “the god of this system of things,” Satan the Devil. (2 Cor. 4:4; 1 John 5:19) As Christians, therefore, we need to watch our associations. God’s inspired Word declares this fundamental truth: “Do not be misled. Bad associations spoil useful habits.” —1 Cor. 15:33.
5 To avoid spoiling our useful habits, we must not have as close associates those who practice bad things. This applies not only to associating with unbelieving wrongdoers but also to associating with those who claim to worship Jehovah but who deliberately violate hislaws. If such professing Christians engage in serious wrongdoing and do not repent, we do not continue to associate with them.—Rom. 16:17, 18.
6 If we were to associate with those who do not obey God’s laws, we might have the tendency to do what they do in order to be accepted by them. For example, if we were to have close association with sexually immoral people, we might be tempted to practice immorality. That has happened to some dedicated Christians, and some of them were disfellowshipped because they were not repentant. (1 Cor. 5:11-13) Unless they repent, their condition can become like thatdescribed by Peter.—Read 2 Peter 2: 20-22.
7 Although we want to be kind even to those who do not follow God’s laws, we should not become their intimate associates or close friends. It would therefore be wrong for one of Jehovah’s Witnesses who is a single person to date such an individual who is not dedicated and faithful to God and who does not respect His high standards. Maintaining Christian integrity is far more important than becoming popular with people who do not live by Jehovah’s laws. Our close associates should be those who do God’s will. Jesus said: “Whoever does the will of God, this one is my brother and sister and mother.”—Mark 3:35.
