Poland won`t destroy anything coz, under PiS rule, we are too weak and unimportant
That's decades of mental conditioning and implanted (for many) - during communist era - inferiority complex talking.
Poland is well capable of defending its own rights and changing the course of the European politics. And especially since similar changes took place in some other EU countries where we can find allies.
Poland - by means of Polexit.
I wish they would. Unfortunately they want to stay in this neo-marxist structure. The only way to change their mind is convincing majority of Poles to become EUsceptic and the party will have to follow. Konfederacja is the only truly EUsceptic party.
And how to do that? By showing regular Poles not abstract concepts but real concerns about how the EU wants to interfere with their normal lives and how they want change them for the worse.
To show them the truth that Brussel "elites" wants to destroy our natural order with islamization, enforced multi-kulti, refugees ("refugees" won PiS 2015 elections), militant LGBT movements (this has greatly helped Duda to win also), anifa thugs (like in the US quite recently), "liberal" media attacks on Poles marching on Independence Day calling them "fascists" and "nazis"
And as a counter-balance to show them the vision of an independent European nation-states bonded by trade agreements and not by centralized political control coming form Brussels.
Another important thing which will help greatly is the fact that soon Poland will become a EU net payer so the sacramental words of EUenthusiasts that "the EU gives us money" will loose its power.
