This is honestly why I don't participate in lj communities, so many of them more and more are becoming HIVEMIND and you just can't have a real discussion without being dogpiled by the hivemind if you ever disagree.

Some of the bigger communities are safer because more people just equals more opinions. But you have to be careful because not ALL big communities are that way, a lot of big communities got taken over by small groups of the hivemind who eventually made others quit or at least ignore the community.
