Paradox #1
The contradiction or inconsistency could be that "Titus 3:2" advises people to avoid speaking evil of others and to be gentle and humble, but there are other parts of the Bible where there are instances of harsh judgments or criticism of certain groups or behaviors. This might seem inconsistent to some people who see a tension between being gentle and the candid criticisms found elsewhere.
