I don't think the article was tongue in cheek. But look what the writer did:
He outraged the GCA types, stirring them to action with emails, posts, complaints.
He probably got knowing, chuckling nods of approval from the non-GCA folks, who on my guess make up 95% or more of the golfing public.
He got noticed, talked about, and remembered. No milquetoast there.
Successful article, from his and his publisher's point of view. That guy might go far.
