Actually you are the one that used obscurity in first. And the only applicable way to apply it was in that OS X is obscure to the hacker movement. Meaning out of the millions of hits they get per day only a few are from OS X...so it’s obscure. True you can change the definition to minority, but you are the one that chose to use obscurity as the word first.
I used the word obscure. I did not misuse the security concept known as "security through obscurity" as you did. I know the anti-Mac crowd does misuse it in this way, as this isn't the first time I've had to smack down this false claim.
In any case, your use of the concept was incorrect, whatever word was used. Minority doesn't necessarily mean safer, and obscurity is used in valid ways in security. Nobody would laugh as you claim.
