It occured to me that it's going to be easier to understand some arguments here if we can know the nationality of the people involved. I've added a (non-obligatory!) field to your profile so you can set this info. It will display to the right of all your posts, and on your profile page.
If you've already created a user, you can add the info whenever you want - click "user control panel" at the top left, then on the "profile" tab, a "Nationality" field will appear right at the bottom.
