Apart from anything else, 'protest' doesn't mean 'complain against' in that context. It means more like 'overstate the case' or 'claim extravagantly'. As in 'protestation of affection'.
Can I also have a MacbethFish for people who say 'Lead on, McDuff' (it's 'Lay on, McDuff' anyway, and it doesn't mean 'come on me old mucka Duffy, let's get moving'), and a JulietFish for 'Wherefore art thou...' when they mean 'where', not 'why'?
Putting my academic hat on
