The heart of what Sister Maureen has to say is this:  "Such a club could serve as a forum for dialogue on LGBT issues, and it was clearly meant to do that."

"A forum for dialogue."  Imagine a space where Catholics can speak to each other on any subject, explore ideas outside of the boundaries of pre-set limits.  Imagine dialogue not limited by Catholic DDT - dogma, doctrine, teaching.  That can come and add to the subject being explored, but first there must be a telling and listening, an exploration of reality, of life as it exists and is experienced, and is known.  And then, after some clarity of what is real, it can be better seen how Catholic DDT is to apply.  

Perhaps we can also see how Catholic DDT needs to be reformulated so that it deals with what is truly dangerous or bad without poisoning what surrounds it, the rest of the human and natural ecosystem.  Life is more complex and interrelated than Catholic DDT anticipated.
