No, that's not what they're saying. They're saying to make a big jump from your T3i to a 7D or a 5Dii or iii. I don't think anybody would argue that a T3i to a 60D would be enough of an improvement to be worth the money. Maybe a 7D, but not a 60D.
O.k. Then you're saying that I'd be better off selling my t3i, 70-200 f4, 55-250 & 50mm 1.8 lenses to purchase a 7d.
I still consider myself a noob, but I'm not sure I can be convinced that a 7d + 18-55 kit lens would be more productive than my current setup... But that is exactly what this thread is arguing.
