Modern computers have opened other avenues to bad association. Some commercial firms enable subscribers using a computer and a telephone to send a message to electronic bulletin boards; a person can thus post on the bulletin board a message that is open to all subscribers. This has led to so-called electronic debates on religious matters. A Christian might be drawn into such debates and may spend many hours with an apostate thinker who may have been disfellowshipped from the congregation . The direction at 2 John 9-11 underscores Paul’s fatherly counsel about avoiding bad associations.
Looks like they ignore Jesus' words once again.
Matthew 9:9-13 (New International Version)
9 As Jesus went on from there, he saw a man named Matthew sitting at the tax collector's booth. "Follow me," he told him, and Matthew got up and followed him.10 While Jesus was having dinner at Matthew's house, many tax collectors and "sinners" came and ate with him and his disciples. 11 When the Pharisees saw this, they asked his disciples, "Why does your teacher eat with tax collectors and 'sinners'?"
12 On hearing this, Jesus said, "It is not the healthy who need a doctor, but the sick. 13 But go and learn what this means: 'I desire mercy, not sacrifice.' For I have not come to call the righteous, but sinners."
Or Paul's direction here
1 Corinthians 5:9-10 (New International Version)
9 I have written you in my letter not to associate with sexually immoral people— 10 not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world.

1 Corinthians 10:27 (English Standard Version)
27 If one of the unbelievers invites you to dinner and you are disposed to go, eat whatever is set before you without raising any question on the ground of conscience.
All the best,
Stephen
