The main reason is that Draco insults Hagrid when he and Harry were 
in Madam Malkin's Robes for All Occasions [PS, chapter 5].  Hagrid 
was Harry's rescuer, a surrogate father for the orphaned boy, and his 
new father was being attacked viciously by this bloodless git. Draco 
also showed that he was an awful snob, and hinted at his pureblood 
racism.  Even if Harry didn't know the issues at that point, he could 
pick up on Draco's tone.  I gave this more weight than you did, 
apparently.  It didn't surprise me at all.  And who says that Harry 
has to choose between Draco and Dudley, anyway?  They are both 
hateful, in their own way.
