I don't think any of them changed really. Some of them changed in scope, but they all retain their meaning.
That's definition creep though,
Hacker means "a person who delights in having an intimate understanding of the internal workings of a system, computers and computer networks in particular." - which is a positive view, but have you ever heard the word "Hacker" used in anything other than a backhand in media today?
Today we have Grammar Nazis (Autocratic personality who enforces "correct" use of language), Jew (which is offensive) and Jewish (which can mean anyone who purtains to be Jewish - regardless of ideology or ethnicity), Hater : a person who expresses intense feelings of hatred or spite, when the reason for this is perceived as unreasonable or spurious, newfags/oldfags (from the original private School version of fags - because I doubt all of 4chan are effeminate/homosexual), and racism; which is now a perceived influence on someone due to their perceived racial agenda - rather than the perceived influence of someone due to their ethnicity.
And most of the countries that have Racially charged political lobbies are those that have more stringent human rights than those countries that don't. That is why such countries have problems with mass immigration, because those immigrants are usually fleeing persecution in their own countries from issues including (but not restricted to) racism.
