It doesn't matter to these people. They are so drunk on their feelings of superiority that they'll dismiss anyone with first-hand experience as an "apologist", a "foreigner" or whatever. They need to perform these mental gymnastics because they've been told all their life that "liberal democracy" is perfect, and anyone who challenges this notion is somehow deficient. To even consider a different point of view would bring their entire worldview crashing down, and so they will twist and turn your every word against you.
