This is a hard line when you think about it. But it is a right one. It protects and embraces our ability to be individuals and to have support and kinship with others like us. This does not mean that I agree with the rules- but it does mean that I respect the group’s organizers ability to make them.
There are many groups that I do not qualify for, and aren’t allowed into - some proudly- and I have a right to my voice. Should I choose to use it.
You bet it is. Groups by their very nature are discriminatory; they have rules of inclusion and exclusion that define that. But- that isn’t a bad thing. This allows others of like minds and experiences a safe place to come and be.
This is a gift.
