What country are MLB fans from?

I was trying to buy some Brewer's tickets, and needed to create an MLB.com account before I could get tickets. I'm curious what country most people are from who do this. When I got to the part where I had to select my country, *required field, I had to scroll way down near the bottom of the list to select 'United States'. The first two choices were: -- and Afghanistan. Is it that hard to put the country most of the baseball fans are from (hint: if you can read this you're probably in it) at the top of the list?
It's not as if this is the only place that does that. I haven't kept track, but would guess that they haven't done that on at least half the times I have had to choose from a list like that.
Now that I've wasted my time scrolling through the country list, and then more time complaining about it, my tickets have probably been sold in the meantime.
