I suggest less xenophobia, look at each lady as an individual wherever she is from.
I think the most xenophobia comes from British prossies who are jealous because they are being undercut, by prettier, younger thinner women.
Personally, speaking I haven't seen a bad EE girl, I've seen bad ones from the UK and Thailand. The worst for attitude seems to British, but that might because the majority I have seen have been British!
I think if someone is EE, it is easy to hold their nationality against them as language can be a problem, there might be cultural differences in attitude and there might just be a girl doing a (blow)job she doesn't want to do. Either way there is no excuse for extra non-agreed on charges or the old-age excuses: you're too big for anal, I have sore gums, I didn't write my profile etc.
I agree that the WG should be judged on her individual merits (if she has any), rather than her nationality.
