Not when the whole thing is sold to the person as a legitimate project precisely to make sure that the channeler doesn't just shoo away the weirdos and goes on about life with his powers unchecked. You can read the character if you'd like, it's all there. But I guess you're right, it is easy for people to be swayed by spectacle and there is comfort to be found in simply going along with whatever large groups of people are doing. Would still like a GM response, assuming a case like this can't be all that rare and that there are situations where it's best to educate the channeler for his own good and the good of others, even if they're not all in on it.
