If the reason you don't like it is that there's a social stigma about looking that way then the stigma is the problem to be fixed.
It isn't a "stigma" to think that some attributes are unattractive. would you think a woman with a completely gray hair is attractive? or what about a woman without hair at all?...

Lets test it with my previous question, would you think a woman with a completely gray hair is attractive?
Ridiculous sexism.
Its not sexism its a fact. Its very common for women to look for older men and its not cause of "daddy issues" as some people say(this whole theory is just sick) it is all about money, a young person will probably have much less money than someone old and is much more likely to "take care" of all of the financial problems of the woman than someone young and good looking that know that his attractiveness isn't related to his money.
And the fact that grey hairs can occur in youthful, fit people doesn't make you stop and think that perhaps there's nothing wrong with grey hair at all and that it's just something pushed by certain groups within society...?
Nobody "pushed" the fact that gray hair don't look good. It is simply a something that the great majority of the population feels whether they admit it or not.
Citation needed that age of hair greying is correlated with genetic disorders. This is a science forum, you can't just yell out "bad genes" and expect a knee jerk reaction of agreement.
Nobody mentioned "genetic disorders". The genetics that make somebody's hair to go gray early is bad and is a problem that should be fixed.
More ridiculousness, driven by your unwarranted assumption that grey hair automatically is widely regarded as unattractive. Even if it were there is certainly psychological benefit to being content with one's appearance. That isn't denial at all. As for the fat acceptance movement I think you've completely misunderstood their point, which is that there is a great diversity in attractiveness (more than is pushed in most media) for different people and we should acknowledge that. Being overweight adds the extra factor of health, which grey hair does not have.
Most people including you and everybody else who "accept" gray hairs don't actually like it or think it is attractive. Why do you think that it is much much less acceptable for women to not dye gray hairs?, cause they wan't to ACTUALLY look good and not just having a look that say: "I am an old guy with a lot of money and I will financially support any woman that will date me", and if this is exactly what you want than why hiding it and talk as if gray hairs really look good?. There is no psychological benefit in trying to lie to yourself and ignoring the truth and this is denial and the exact thing the "fat acceptance" are doing, being fat isn't attractive and if it was attractive they obviously wouldn't have to try and convince people that they are attractive, someone might be attractive DESPITE being fat but this is a completely different thing and it isn't common. And I am not talking about health at all.
Again this is a science forum; terribly constructed arguments are not going to fly here. Attempting to conflate the idea that grey hair is an absolute factor in attractiveness and a factor in health with personal preferences in partners, then setting up a terrible false dichotomy.
