Beware of the group proudly preaching inclusiveness while brushing off those who fail to meet its unspoken rules and criteria. Such a group is in a state of collective delusion. Every group has parameters for inclusion, whether written or unwritten. To pretend that these parameters do not exist — or, worse, to pretend that they have been magically dissolved by the high moral will of the group members — to waltz with a most pretentious hypocrisy. Why? Groups and communities exist precisely because they represent a subset of the population; a contrasted segment of the whole. When a group announces that it is open and accepting of everyone, it has only tricked itself into thinking that its own unwritten values are universal. Could this be the reason why groups that are most judgmental and critical of outsiders are often the very same groups claiming that everyone should join them?
