“Creed” [0] is a protected class and it will be interesting to see a legal determination if this is discrimination based on the creed of the organization. Namely, carrying out its congressional mandate.

I think that social constructs could be discriminated against based on race, religion, sex, etc if it was discriminated against because its members were part of a protected class.
