Alma 14:7

7 And it came to pass that he began to cry unto the people, saying: Behold, I am guilty, and these men are spotless before God. And he began to plead for them from that time forth; but they reviled him, saying: Art thou also possessed with the devil? And they spit upon him, and cast him out from among them, and also all those who believed in the words which had been spoken by Alma and Amulek; and they cast them out, and sent men to cast stones at them.

There must have been many who felt what he was saying was true enough to openly and publicly defend it, because they were now known as believers and were cast out and stoned.

(And worse coming up. This part is hard for me to ponder.)
