[What Giovanni says is undeniably true. From their first days in ALASTAIR — he recalls them being new at the same time — their team was deeply divided. The question of whether to sacrifice a world's deities to prolong its life for an unspecified length of time had been and gone, by the time the two of them arrived on the scene. A choice had been made, and Haise recalls distinctly the disappointment that had seized him then, clamped down tight around him with his sense of unyielding futility.

Back then, though, he remembers the people who reached out to him. Who spoke to him and explained their reasons behind their individual assent or dissent. In all of those cases, he recalls no hostility directed at him, though strong opinions existed. He had the sense that he'd missed the most heated of discussions.

Now, of course, he's present for everything. He understands more, but as Giovanni has said, strong views don't leave everyone terribly receptive]

That's a choice no one will take from you here.

[He thinks to remind him, because it's important. The other man isn't chained to the reality of his world now, isn't confined to the reality in which he'd once lived. It is his choice. And in this way, he can subtly express that he hasn't forgotten what Giovanni's will is]

It does seem difficult to get the lines of communication open, especially where those deep divisions don't really inspire trust or comfort in expressing oneself freely. A suggestion was to have people meet in-person, which may fare better than remote communications.
