That is a valuable perspective and all, and I don't discredit it (or concern for curbing illegal immigration as a top policy priority in general), but I'm not sure it's that persuasive for the point you are trying to make.

Let me put it this way: pointing to one cogent article by a non-representative Trump supporter (you won't find many of them in academia, and the college-educated skew liberal/Dem) doesn't really make me change my mind about writing most of them off as racists based on my personal experience and what most of them say (which is not as cogent and reasonable as this guy's article).
