I was wondering what the heck you were talking about until I came across this paragraph:
And now I see why you ask your question.
The pairing of “polemical” (which means harshly critical) with “apologetic” suggests that the Pope is referring to the type of apologetics which is not allowed on this Forum (and which will get you banned) - nasty, sniping behavior. The kind of thing you would find on
carm.org every day.
I’m sure the Holy Father does not mean to discourage respectful and reasoned dialogue about religious differences, especially when people come to us (Catholics) with these questions. Every non-Catholic that is here came here willingly.
He holds up the example of Jesus and the Samaritan woman (a Jewish heretic) to encourage us to engage with those whose beliefs differ from ours.
