So, I sat back a bit and watched the mayhem in this thread.
Let's say, they spend about a bah-zillion dollars, 20 years, and risk the lives of thousands of test animals + researching and testing on human subjects to produce a safe and effective way to change hair texture. In either direction. Straight hair for the curlies, and curly hair for the straighties. There are no major side-effects, it is as safe as taking, I don't know, aspirin for a headache.
Let's say, for the sake of argument, that I decide to take the pill to make my hair curlier. Let's say that I have so much trouble dealing with my own hair, that the thought of having a child with this hair and then having to manage my own head and my kid's head looks like a daunting insurmountable task. Let's say, that I take this pill in hopes of developing a massive, head swallowing, billowy 'fro. The kind of 'fro that I've seen women on this board swoon over. And the idea that my child would then come out with this hair is something I look forward to so as to save myself the problems that come with my own hair type, and I would be saving my child from that same headache.
I would then be hating myself and my ancestry?
My preferences, likes, dislikes, tastes, history, culture would be automatically discarded and invalidated by people who don't know me, and I would be branded as "self-hating". There is a strong stigma to that terminology, as far as I see it, it is an insult. I see the use of it just as bad as calling someone by any other racist word. You pick the nastiest, most disgusting pejorative you can think of, that's how I see it.
I fail to see how insulting people for the choices they make is tolerant or accepting of other people.
And no, I wouldn't take this pill, I'm quite happy with my natural texture. I'm just sympathetic towards anyone who is criticized for wanting to make changes that they see as self-improvement for themselves. If the option is out there, and someone chooses to take it, then good for them. I'm not dealing with their hair, so I'm not going to pass judgment on what they do.
