Yet other SS advocates do reject Tradition.
From Wiki:

Main article: Sola scriptura
It means “only scripture” and it excludes church tradition and church interpretation as elements to define doctrine. Sola scriptura is the teaching that the Bible is the only inspired and authoritative word of God, is the only source for Christian doctrine, and is accessible to all—that is, it is perspicuous and self-interpreting. “Scripture interprets scripture” is a governing principle of many Protestant denominations.
And with no magisterium to speak for the definition of SS, no one can say, “That is NOT what SS means! You can’t reject Tradition!” for the author of that proclamation simply has no authority to tell another what his definition of SS is.
