> Did you know there exist spiders in our world that can kill you if they bite you? Sensible reaction.

I'm Australian, so yes, I am very aware there are spiders that can kill you. However, that doesn't suddenly make every spiderweb a threat. The reaction may have a reason behind it - but it does not mean that there is any threat present.

Lets try putting it another way.

Children are often frightened of the dark. This makes sense, as they cannot know what is in the dark, and the dark _may_ hold a threat.

This response on behalf of the child in no way says that there _is_ a threat. In all likelihood, there is none.

Responding to something as if there is a threat doesn't suddenly turn something benign into a threat.
