I think, given the specific comparison of speak in statements versus speak in apologetic questions you should interpret the meaning thusly:
If someone is making religious apologetic statements then one is taking something that the religion believes is true and turning it into a question. For instance:
Statement: Bhudda's teachings are truth
Apologetic question: Are Bhudda's teachings truth?
Statement: Bhudda taught us an enlightened way to live
Apologetic qustions: Is the path of Budda really an enlightened way to live?
Statement: God exists
Apologetic question: Does God exist?
Statement: Jesus was the son of God
Apologetic question: Was Jesus really the son of God?
This process can be extended to everyday life:
Statement form: After work I'm going home
Apologetic question form: Am I going home after work?
Statement form: I'm Batman
Apologetic question form: Am I really Batman?
Statement form: We are currently living in a yellow submarine in the land of submarines
Apologetic question form: Where are we?
I think the basic advice is that, just as apologetic questions turn something that is believed to be a true statement by a certain religion into a question, anything can be presented as either a statement or a reverse (apologetic) question, and the advice is to present it as a statement not as a reverse (apologetic) question.
This advice can be very helpful in all sorts or areas, such as sales:
Statement form: My product will add ten years to your life!
Apologetic question form: Do you agree that my product may be able to lengthen your life?
Such as politics:
Statement form: Pulling all our troops out of Iraq is the right decision!
Apologetic question form: Do you think we should leave a residual force so as not to create a
power vacuum that could invite a hostile force to take over?
Such as acting:
Statement form: I'm Batman!
Apologetic question form: Do you think I make a believeable Batman?
