Spot on, fella.
Are you a white person whose family came from Europe? Were you born here on United States soil? Do you think and act like an American?
Then guess what, chicken butt? You are a white American, and I literally don't care how long your family has been here.
These heritage American people sound like those insufferable faggots who get mad because a band got famous, but they were listening to that band since they were selling mixtapes out of the trunk of their car. "MY FAMILY WAS A FAN OF AMERICA SINCE DAY ONE, MAAAAAAN!"

I understand that with cases like me there would be a certain amount of distrust since even though I was born here but I didn't live here until I was 14. If someone wanted to be a dick they could just say "Well you're an Aussie, it doesn't matter that you were born in America. You have that faggot crocodile hunter accent so you'll never be an American."
Fine whatever, take people like me out of the equation. But to tell Michael O'Malley that he's not a real American because all four of his grandparents came over from Dublin in 1923 is fucking ridiculous. What do you think that guys walking around speaking in Gaelic exclusively and getting into Donnybrooks with other clans at the local tavern? Fuck out of here with that.
