unfortunately every time i've come into contact with gypsies they have justified the stereotypes.
Every time you've come into contact with one? You could've said hello to one this morning, been served by one in a shop, sat in lectures with one the other day and how would you know without asking? While we're at it, are we talking Romany gypsies, hippy new age travellers or what are known as 'tinkers' over here?
It's still stereotyping to me, however noble your stated intention to 'judge any future ones you meet on an individual basis'.
Prejudice is something that human beings tend towards partly naturally and partly because of conditioning. The latter is something which education and tolerance can help to break down.
Believing that stereotypes have any foundation other than popular prejudice is to take the first steps down the opposite road.
