@Germlat,
An idiot needs to be told, or they'll never realize they have a problem with logic and common sense.
A child needs direction, and many don't ever grow up!
I'm not sure what kind of world you live in, but I've experienced all manners of discrimination and insults. I do not remain quiet.
From the time I was a young child, I wore glasses, and many kids picked on me. I learned that fighting with them stopped the taunts. Humans do not change just because they add years to their lives. That's psych 101.
I've been in many kinds of social environments, and can hold my own in most.
I don't need anybody to tell me how to act at my age.
Train your own children. I raised two sons, and they're good people with above average intelligence.
I've been an advocate for all groups who do not enjoy equality, and the two charities that I give donations to every year are those that do not discriminate in any way.
I've traveled to over 200 countries, and pretty much understand how people live in both rich and poor countries. All people are the same; they want their children to be healthy and happy.
