I think that by saying ones own country is better than another without any GOOD supportive evidence is nonsense.
We all speak English so we should all be treated as equal. All of our countries have their bad representatives, but they also have good ones. It really makes you think, "Why do we bother having good representatives when all other countries want to do is look at the bad ones?"
In my opinion, when one English-speaking nation insults another, it's almost like insulting your own brother. Now I don't want to hear, "Oh, well i insult my sibling all the time because i hate his/her guts." Metaphorically speaking, you're brother is your family, and even if you don't always get along, you will always be brothers.
