Disagree, Regina's magic/blood was only used by the Coven as one of the ingredients to cast the curse. She was blackmailed into participating in their ritual, but it does not make her a member of the Coven.

I for one am not sure where in the thread you got this idea. From my reading it seems there is broad agreement that Regina participated in the casting ritual through her blood being given, but nothing about anybody agreeing that she was a member of the Coven.
