How much does what a person's avatar look like influence how you respond to them?

I saw some great new avatars yesterday and was inspired to change mine, although I don’t know if I will stay with it.

There are some of the default avatars that I am not too keen on since I view them as looking like skulls. This one and this one.

I am also interested in avatars when I can’t quite make out the image. My favorites are still the hand-drawn jellies. How do you feel about them? Do they impact how you react to people’s answers?
