I believe that but it depends in what context you place that statement. As a minimum, for example.
Is he looking from the top down, or the bottom up?
It's easy for a driver who assumes (and we do as well) that he will be the quicker of the two, to say "I want equal treatment" because he knows he's going to get it. Looking at it from a slower drivers point of view, as long as what Alonso is getting is the same as what he is getting then it's all fine and dandy, but once the points start getting banked and as we know, points mean prizes then the quicker driver will get the better parts, the newer bits etc. That's the nature of the F1 beast.
So, yeah, of course Alonso can say, he wants to be treated equally but to paraphrase George Orwell, all top drivers are equal but some are more equal than others.
