The problem with groups is the danger of creating what I call "intellectual incest" as well as "groupthink". People who become addicted to groups come with issues that cannot be addressed because the needs of the group do not allow people to address their individual needs.
Damn Straight!!!
To add on here, there is a specific reason that the needs of the group don't allow for individuals to TRULY address their needs. This needs to have all kinds of spotlights on it.
The reason is because the more people REALLY address their individual needs, the more free they become to live and operate independently of the group, and the more the people move toward the direction of personal autonomy and sovereignty. This causes folks to become more in tune with the desires of the heart, which usually conflict with group aims and objectives.
Many people have a psychological and emotional reliance on the group - for states of mind and well being, that in reality are best addressed when people deal with and heal themselves.
