To the "they took away my gay word" brigade
Here's how language works (all of them)
1) People make sounds that have specific known meanings
2) Sounds and meanings change over time.
3) Er, that's it.
If a set of people decide one day to start using the word 'sick' to exclaim how good something is, there is no objective reason for this being a bad thing. Wind forward 100 years and the meaning might have died out or become the only 'correct' way to communicate such an idea. We can't know now, but moaning about it shows how little you know about how our language is what it is today.
'Gay' has gained a new meaning, and the old one has become archaic... but it might not have done. It isn't all that long since people started using the word 'fruit' to describe homosexuals. Did that destroy the use of the word 'fruit' to mean apples etc? No. Of course not.
Nobody will give a damn if you want to continue using a word to mean an archaic meaning. They just won't understand you. Is that what you want?
This is language. Deal with it!
