I know that in several countries I have lived in I have been robbed and attacked at gun-point by people of a different colour to myself so the question is then a simple one: Am I a ''terrible racist'' because I am confronted by such people again and start to feel that I need to be ''on my guard'' and cautious? For me I think not but opinions (I am sure) will vary here...
It is called 'to use previous experience on future situation', which is what we all do all the time.
You stick your finger into a flame and get burned. Repeat. At some point in time your experience tells you to mistrust flames.
With people it's more complicated. That you have been attacked by people who have e.g. green polka dotted skin raises your alert when you see someone with green polka dotted skin - especially in a specific environment. The majority with 'gpds' won't attack you, they are common, gentle folks.
I have been attacked by youth gangs (four youngsters each time - lack of self confidence?) twice within a half year in Chile, they looked Southamerican.
After each incident it took several weeks for my body not to release a rush of adrenalin and rage when I saw 3-4-5 Southamerican looking youngsters in a group at night in a more or less deserted street (had to walk through the streets, no taxis, busses, etc. to be had).
As long as you don't get paranoid about it, this is not racism or some similar attitude, but simply using your past experience to avoid future trouble.
Racism is to have a negative attitude towards people with certain enherited traits, based on these traits
only, like "I distrust/hate people with green polka dotted skin" "Why?" "I just distrust/hate them, people with green polka dotted skin are bad!".
