Being proud of something that is not your accomplishment means not understanding the word "pride". Being proud of your country, religion or ethnicity is a sign of idiocy.
It starts from the fact that countries and religions are constantly competing with each other, and in order to compete, they must create armies of cannon fodder - people who are willing to sacrifice their own well being for "the greater good".
The better the country/religion is in creating such people, the greater are its chance of survival. That is why 'current' countries and religions are very good at this. They raise children to be "proud" of them, because that makes them easier to manipulate.
Whenever you see a person that is proud of its country/religion, you should know that you are witnessing such a "cannon fodder" person.
