That article is all about " peacefully coexisting"
Why should it be otherwise?
Would any of us ever say to someone " your father was an alcoholic, and your whole family is dysfunctional. Therefore you are defective and abnormal?" It's absurd. So isn't it wonderful when people take a more " sober" view, in the inner faith community. Particularly when these people do more than simply " peacefully coexist" . They also become proactive in the community, thus demonstrating what " peacefully coexisting" in a multi culture society requires.
