I urge you to read through his posting again (slowly). You're phrasing (or closer, shoehorning) his article and your response as a mentorship versus hostility debate, but it feels a bit straw-man-ish misrepresentation to me. Let's keep shifting the other author's position to the "evil" side.
Though, again, perhaps I'm wrong. Maybe it was a "terrible," "ugly," and (now apparently) "hostile" article. However, you'd need to point out the directly hostile parts to me, in that case. Because I missed them.
>That's not what makes the asshole.
Oh, you. So cheeky.
