Why is Nancy so afraid of debunkers?

She bans people who don't agree with her.

Maybe because she's trying to prop up the facade of her lies over the years.

Somebody said once, that the truth doesn't need to be defended. The truth will stand on it's own.

Fear is a symptom of a deranged mind at work. A mind that is totally deluded in a false belief system, A mind that can no longer grasp common sense.

Nancy is trying to be a soothsayer, and she's not very good at it. You could go the the local county fair and get a tarot card reading from a carny and do better than Nancy.

She is a fraud.

Look at how her few followers are closed minded and vulgar, nasty and rude.

It sucks to defend a lie to the point that you are no longer a nice person.
