The thing is, I don't feel this is a bias. It's the same as with smokers, alcoholics, drug users and others. Their shitty lifestyles cause problems to others (smokers - smoke, alcoholics - aggressive/broken bottles on the ground...). That's a fact and not hard to prove. Hams do different things but the principle is the same - other people pay for these idiots' shitty decisions. It would be a bias if hams only complicated their own lives and not other people's - but they don't.
