re: Is "racism" genetic or learned?

I think some people mistakenly equate someone having a preference to be with people of their own race as being racist.

Several years ago I read about an experiment that was conducted using different types of snails.

A bunch of different types of snails were put in a box together and dumped into a closed canyon to see what they would do when released.

When the scientists came back a month later to see what the snails did, the scientists looked for the snails and found out that all of the snails of the same type had segregated themselves into a group away from all of the other types of snails.

Does that mean all snails are racists?
