I don't think you could simply replace RoR with java (J2EE) in this particular post. But even if you could: you'd be right to cap on java.

Java makes programming difficult. Some people like that. Many don't.

Ruby makes programming easier. RoR makes doing webapps easier. This guy's premise, that there is no overarching philosophy to RoR, is incorrect, and shows unnecessary ignorance and anger. You have to wonder if he's just projecting.
