I don't think Mr. Alexander has had this conversation with anyone in bioinformatics, where "SNP" is universally pronounced "snip" and given the preconsonantal indefinite article - "a snip", not "an ess en pee".
Like a lot of stuff that comes out of the rationalists -- autodidacts with a background in stats have decided that reading research papers on their own is a sufficient approach to knowledge, with often pretty messy results.
His actual reading appears to be spot on, which ia fairly impressive, and well nuanced besides with regard to reliability of results in a field not especially meriting respect for its rigor.
