I have a sense of pride in my country. There are so many beautiful nations with wonderful cultures and lifestyles. There are some that are not so much. I don't hold that against them unless they had a choice in the matter.
I do not appreciate when my own countrymen put our nation down. Especially for things that happened in the past. You cannot judge the past by today's standards.
If persons from other nations put my country down it doesn't bother me so much. Haters are going to hate.
