My Only Wish

Since I have lived 365 Earth months, I have but 1 Wish for today, along with my advice, but for today I will simply call it, "My Only Wish". 

I WISH humanity would stop segregating each other by our differences. 

Isn't it about time we listen to the advice history has passed down?
Isn't it about time we learn from their history? 
Isn't it about time we teach those morale history lessons?
