Ladies, for the record, I'd like to say that although I can't speak for MsChys79; I don't think that she intended for to remark to be taken in such an inflammatory way. In real life, I hear the term "good hair" tossed around way more casually than I'd like, and I usually take the time to voice my displeasure with the speaker. I've found that most people who use the term don't even realize that it's offensive in the first place, nevermind WHY.
This term is tossed around a lot in the American Black community, and my Dominicanas, toss around the term "pelo malo" quite frequently as well. If you're familiar with either term, then you know what they both mean. My problem with both is that both imply that highly textured or nappy (and I don't find nappy to be offensive, btw) hair is bad, and that implication is incorrect, and can be a blow to someone's whose self esteem isn't up to par, especially little girls who are subject to hearing ther mom's complaints about their hair every time they sit down to get their hair done.
Just my two pence.
