FYI, Here is a little history on your choice of the word bigotry.
Word History: Bigots may have more in common with God than one might think. Legend has it that Rollo, the first duke of Normandy, refused to kiss the foot of the French king Charles III, uttering the phrase bi got, his borrowing of the assumed Old English equivalent of our expression by God. Although this story is almost surely apocryphal, it is true that bigot was used by the French as a term of abuse for the Normans, but not in a religious sense. Later, however, the word, or very possibly a homonym, was used abusively in French for the Beguines, members of a Roman Catholic lay sisterhood. From the 15th century on Old French bigot meant “an excessively devoted or hypocritical person.” Bigot is first recorded in English in 1598 with the sense “a superstitious hypocrite.”
Also looking into the definition of bigotry you are faced with several for consideration. Taking the obvious meaning you have projected:
2. A person who regards his own faith and views in matters of religion as unquestionably right, and any belief or opinion opposed to or differing from them as unreasonable or wicked.
It sounds like Billy to me. He has publically admitted that the only way to heaven is through Christ. Thus in the true sense of the word, he is bigoted toward not just Jews but all others that do not believe in Christ. His mission is to save them from damnation and guide them into the grace of Christ, which means he loves them despite the fact they are wicked and of the world.
I would gather that he also knows that no man is free of sin, including himself.
I see that you have accepted his apology, which is good of you, do you also accept that Jesus Christ is the Son of God?
