Considering how some obsessive and uncompromisingly disagreeable mudcat 'personas'
display character traits and behavioural patterns
that are so reminiscent of very difficult folk we occasionally encounter in the real outside world..

We should be more alert for signs of Undiagnosed Aspergers Syndrome or Sociopathic Personality Disorder...????

Also we should be aware and sympathetic towards inevitable physiological effects of the ageing process
manifesting in increasing antagonism & belligerence in many individuals.
