You will find that Fido's theories only 'work' in a functioning law obiding society. It's like an unemployed person saying 'it's my right to be unemployed and on benefits' - that sort of attitude only works in a society that is mostly employed - if everyone was unemployed there would be no welfare and he would have no choice but to work to survive (ie his theory about his 'right to welfare' would not exist)
Taking that a step further - there is a reason that Fido refuses to look at what occurs in a society where law and order has broken down, or barely functions (as a comparison to one that is law abiding)
There will also be a reason why Fido will refuse to look at why he can have a peaceful, orderly trip on any western road in a big city.
He talks about the minority lack of justice in a law driven (large) society, and ignores the much larger lack of justice inherent in any comparable size lawless society.
There is a reason he chose the most reviled law system of recent times as his example for the 'evils of law'...but fails to look at the majority. This is like walking into a candy store and saying 'this candy is bad so the rest of them must be'
His theories are so flawed that I could spend quite some time poking thousands of holes in them. The thing is - the flaws are so obvious that any person with an unbiased perspective should be able to see them, leading to a 'why should anyone bother' attitude towards this sort of silliness.
I don't think him unintelligent - just extremely colour blind. Humanity has a great capacity to justify to themselves (and often to even explain articulately the 'goodness' of) anything from the kindest of guestures to the most evil of deeds.
