No, the fact that you disagree with him about whether it's a delusion, or even if he were wrong about that, does not make his assertion that it is bigotry. Further, I have shown that the definition of "delusion" does not include a requirement that there be invalidating evidence. cf. my cite to dictionary.com. Even further, I have mentioned extensive evidence invalidating the existence of a God who answers prayers at a rate different from if He did not answer them. And finally, I don't think you have a grasp of what the ad hominem fallacy is. It means that rather than say that someone is deluded, you say they're mean or evil, (or bigoted) and therefore their argument should not be accepted.
