How do the Sola Scrptura folks react to the Dead Sea Scrolls and other more recent discoveries of ancient Biblical texts not among those canonized by Martin Luther?

Since the Bible is a collection of writings (literally what biblia means), you will even find that while Matthew and Luke have genealogies, Paul wrote to Titus and Timothy not to pursue foolish genealogies.

Even Jesus questioned how the Messiah was David's son.

The New Testament was established as part of creating a universal (catholic) interpretation for all Christians.

Why do liberals think it is okay to steal votes while the rest of us obey the law(s)?

Nuda Scriptira is scripture alone. Sola Scriptura is writings authority over traditions and does not imply Biblical inerrancy (see above in regards to Jesus, and genealogy to David).

Actually, Luther was influenced by the books of the Masoretic Tanakh and did, originally, include the Apocrypha.

Just as there are a few discrepancies between the Masoretic and Samaritan Torahs.

A protestant (one that adheres to sola scriptura) disagrees with a catholic. How do they propose resolving the dispute?

If you study, you will find passages in the Orthodox Bible, not in the Catholic.

However, if one is using the Bible as a premise and traditions, how does one evaluate discrepancies between the two, as traditions are interpretations of Bible passages as their claim for validation.

In response to A2A:

Is Florida now unsurvivable because it's an oven due to climate change? It's 11:48 am on May 30th and the heat index in SoFla is 100. I can see it going up to over 130 by July.

The influence of the Christian Old Testament was the Septuagint, which predates Jesus. Luther, also maintained the Septuagint philosophy of law, history, poetry and prophets, in ordering, while the Tanakh followed Torah, prophets (Nevi'im) and writings (Ketuvim).
