The teens are into wearing a lot of perfume. It does not bother me and I would not call it "toxic" as humanity has managed to survive with perfume forever.
Some people are allergic to it just as some are allergic to cigarette smoke. We should never shape public policy around the health issues of a few. Some are allergic to the fumes of your car and hate the smell of it. If we do this, we will lose all freedom because anything the elite want to ban, they can do so in the name of health.
I believe that was the subtle point the poster was attempting to make.
