I do not think racism is a think of the past. I do not believe I've ever said that. I don't even identify as white. My DNA has more in common with North Africa than with the Anglo-Saxon groups that created the concept of "being white", so you should check your prejudices.
Racism is really prevalent today against PoC. I've anyone understood anything else from my messages I apologise for not delivering my wording right.
That being said. "White" people is privileged in many areas. Going bald and suffering from balding is not one of them. And invalidating that feeling, saying that a white person going bald should not complain or suffer about it JUST BECAUSE THEY ARE WHITE. Rubs me the wrong way. Millions of white people suffer a lot because they are going bald, trying to invalidate that feeling just because they are white is just wrong.
It's incredibly funny you say I believe "white is the default race" when you directly attacked white people, and your only defence for that offence was that was hair saloons are important for black people. Completely ignoring the thousands of different ethnicities that are neither black neither white. What about a balding Asian? can they complain if they go bald? A balding latin american? Which degree of anglo-saxon DNA has a person have to have in their blood to be able to complain about going bald?
The root of this is that a person say that "white people cannot complain about going bald because they are white" and has yet not retracted that incredibly racist statement.
You don't know what's going on in the life of that balding white person, and you CANNOT DEDUCE IT FROM THEIR RACE. You don't know if they are for instance a trans woman and suffering an incredible gender disforia because the balding. You don't know what importance have their hair in their lives. And trying to invalidate those feelings based only on their skin color is a bad thing to do.
