Full Idea
The idea of equal respect is difficult or impossible to render compatible with a religious establishment, even one that is benign and noncoercive. Any established church (or government secularism) denigrates nonbelievers, by stating they are an out-group.
Gist of Idea
Any establishment belief system is incompatible with full respect for all citizens

A Reaction
This sort of applies to membership of anything. She is sort of right, but there is no reason in principle why full respect should not be accorded to any out-group.
