Ok, I guess I'll just say it.
I think type 4's don't want her to be a 4b, because deep down the insecurity of their hair type/acceptance still lurks, so to pacify themselves they categorize her as a looser hair type because those hair types are the "good" hair types, which explains why (in the good hair/bad hair mentality) her hair is so long and thick, and maybe makes them feel better about working on their hair for so long and not having remotely the same progress.
I think the lower hair types (3 and down) think her hair, despite it's length, doesn't have the "silk" and "shine" that qualify it as "good" hair, so it's like, " i'm a type 3 and that ish is too nappy to be like my hair"
, despite her curl pattern when wet and unmanipulated is a HELL of a lot looser than those who insist on the 4b categorization. Also, even though she has the length, she doesn't have the "right" texture, so there's a bit of, "I have "softer" hair and am stuck at APL, WTF"? A lot of the commentary comes off as disingenuous, insecure and transparent.
How do I feel?
I like her hair, think it's cool, glad she is shaking up stereotypes and antiquated ideas about afroey hair. I think she has a very loose curl/wave pattern, coupled with very afroey textured hair, which is a totally possible combo, just like there are many silky type 4's. I think people's hair hangups/issues are coming thru and it's unfortunate that people's minds are soooo narrow in 2011 after being on this forum and seeing a-z hair types thrive, break, stagnate, etc. I really think the colonial mentality will stay with many regardless of how much proof they see to the contrary.
Basically, the way I see it, both sides are "hating" and projecting but for different reasons. The similarity between the two is the disbelief and/or colonial mentality about hair as "nappy" textured as hers.
