Many countries have done just fine without such additional, sjupefluous bureaucratic entities.
Poland has a constitution which was chosen by the Polish people in a free and fair election. That constitution sets forth rules regarding many things which the PiSlamic State now ignore because they lack the popular support to change that constitution.
who prosrecuted dissidents should have been debarred in 1990.
Yes, the likes of First Secretary Kaczynski and the Party's leader in the Parliament should have been barred from public life, just as the foreigners who collaborated with the commies should have been deported and those who bought state-owned property at knockdown prices should have had that seized. Sadly that didn't happen and it's simply too late now.
the hysterical anti-government anarchy
The hysterical thing is not the protests, those are good humored and make me proud to live in Poland. What's hysterical and hilarious about this are the posts you write, not only are they so reminiscent of the articles in the Podunk County Polish Pig Farmer's Gazette about the bandits from Solidarnosc but they reek of the fear that is dripping of the supporters of the PiSlamic State at the thought that they may have to face free and fair elections (and thus afterwards answer for their crimes).
