Then the criticism should have been limited to that.
What you call criticism could be argued to be nothing more than a concise and accurate depiction. 
- an aging class C tells me that it is not new, and may have worn components, such as suspension, brakes, etc...
 
- towing an old junk car backwards tells me the car is probably in extremely poor condition, and may have suspension, steering, camber/caster issues, bad shocks, etc...
 
- on an old dolly tells me the dolly may also not be in top condition
 
- swinging wildly tells me the rig definitely had some issues with stability.
 
I'm not sure that I see criticism in there.  Maybe not the nicest words, but they do paint a picture of the situation.
