My own definition of the term means if you are not a sede when you die you are ripe for Hell, no doubt about it. Who here says that?
As far as I understand, this is Matthew's definition as well. If there are any dogmatic sedevacantists on CathInfo, they must either hide their dogmatic belief on the subject or they will be banned posthaste.
There are, however, quite a number of outspoken dogmatic
anti-sedevacantists that post their vile schismatic dogmas on the forum with abandon. They are usually the people who frequently condemn all the "dogmatic sedevacantists" because, in their evil, they simply assume that anyone who provides logical arguments on sedevacantism that they cannot answer and that bother their consciences must be dogmatic on the issue since they realize in their very core how untenable their beliefs really are.
