What would you think if I said that I really hate Russians?
Why do you really hate russians?
Because I'm a patriot who thinks my country is better than all other countries.
You should not hate others because of their nationality. You do not know them and it makes no sense to think that way.
But Russians are bad people.
Saying all Russians are bad is just pushing a negative stereotype. It doesn't matter where people come from, there will always be good and bad people.
