I think it is very good of Baldwin to speak of his faith, especially given his notoriety. But one who expresses his faith publicly should be invited to also rationally explain it. “Sanctify the Lord Christ in your hearts, being ready always to satisfy every one that asketh you a reason of that hope which is in you” (1 Peter 3:15).
That verse is intended to encourage believers to share their faith with nonbelievers. It isn't about defending one's faith from the charge of being of the incorrect -ism.
