I'm really really close to posting hawt photos of half naked older men. . .Screw it, here's a model, middle age and "old" looking.

I've seen young people who looks "old" too. They were of all racial background, and they live in harsh conditions such as being migrant workers or homelessness. Perhaps they should think about that.
Then there is subjectivity. I'm in my middle twenties. I may look "young" but compare me to my high school photos and you'll readily see that I ain't no ageless young'un. We age differently. Even the supposedly ageless men of color age too. Usher is still a hot man but he isn't 100% the same Usher from the 90s.
People have all sorts of preferences. Some people like the bear look and some like twinks. Some people like it all. I sometime think these tumblr personalities thinks they're gods or something; they're always above being criticize but they'll criticize ever nitpicking things about other people. That's not social justice, that's egotism. For as much as I loath the anti-SJ crowd who bitch that people are "obsessed" with race, or the anti-SJ crowd who tone troll people, I also loath taking something as trivial as how a person age and making it social justice.
Sum: I'm still that "race obsessed SJW" who see racism in many things. How one looks while aging is not one of those thing (unless we're talking about health discrepancies among older people of difference races which could alter a person appearance as they age, which the OP was definitely not doing.)
