Actually that's totally normal here too. I get called blanquito by randomers all the time when I'm out, and it's not offensive in the least (though it's arguably, in a vaccum, a more offensive comment than negro; negro highlights a desirable trait--tanned skin colour--whereas blanquito highlights an undesirable one--palidness ). In general in spanish it's far more normal to call people by names like 'gordito' (fatty--this is used extremely often as a friendly term, and I'm sure @TheSpecialCnut will tell you he's got at least one friend who's called this, pretty sure we all do), 'flaquito' (skinny/overly-skinny), or simply 'italiano', 'chileno', whatever...here I'm called affectionately by my friends 'yanki' (yankee), and it's simply not meant in any derogatory way (though I wish it were).
Indeed, which is why I find it incredibly strange that you, and @JakeyBoy, and the whole world continues to ignore Evra's part in it. If Suárez is a racist--which I find incredibly absurd to call someone off the basis of some lite as fuck mid-game trash-talk/provocation with a guy who barely even understands the language in which the interaction took place--then by all of your barometers so is Evra, yet I've not heard anyone even address this, or dare to.
Tbh, I think it's pretty clear neither is a racist, given that both have worked under a number of clubs in a number of different countries with a number of different nationalities and not been anything but well-liked and respected in their dressing rooms, but the fact that Suárez was singled out in the issue and not Evra, is again, telling. Why? Well, because racism/xenophobia against south americans isn't a fashionable issue in England or the current political sphere, and because making Suárez out to be the villain fit a very, very easy narrative to work (such that, again, all of you have swallowed it whole).
