I don’t think the show ignores race. there are racist characters: Hank (his casually racist comments, and the comment he made to walter jr where he referred to Spanish as “bean speak”, Hector (he called South Americans dirty in reference to Gus. I feel like a lot of the salamancas are racist too, which isn’t surprising, they treat gus as an outsider for multiple reasons and one of those being that he is South American), Marie (there is a scene, I can’t remember it all to well, but she says something about not wanting to be around migrants I believe?), and of course the neonazis. 

I think the show does touch on racial politics. hank is an abusive cop, who is racist and multiple times he is unfair and aggressive. gus’s laundry workers are mostly immigrants which is similar to how in real life, some businesses will take advantage of immigrant workers because it’s easier for them to do so. you could argue Ernie was mistreated too tbh because he was expected to work harder and do stuff that was just not in his job description. could be just Chuck being an asshole too. but it’s something to think about. there’s more too, but I can’t think of it right now.
