I think examples for questions perceived as skewed are ones like: "Our race has many superior qualities compared to other races", because most intellectual modern right wingers would most likely not agree, and it seems like such an obvious bait, almost like the questionaire is asking "Are you a fucking racist? Say it come on". Put in another way some questions seem to reference an obvious taboo and shame people for being rightwing and pressure them into answering leftist.
I can see why some people would perceive it that way, but the reality of it is, that these questions are normal questions to ask in surveys about national identity, and many people would just agree because thats genuinely what they believe. Keep in mind that forums is a very specific social group for the most part, and not a representation of the broad public, not to mention the different cultural backgrounds.
The nest issue is that this particular questionnaire asks questions like "some people are naturally unlucky", which most people would probably decline in this day and age, especially on forums, but disagreeing with that statement gives you cultural score for "libertarianism", because the authors of the survey operate very strictly along the lines of the authoritarian personaliy of horkheimer. Essentially most of page 5 is not a valid representation of idelogical believes.
anyone interested can for example check out the questionnaires for the 2013 ISSP on national identity. There are being questions asked like: should foreigners be allowed to buy land in x? Should foreigner intermarry with x?

I overall still agree that this particular questionnaire is shit, because it does not follow basic scientific guidelines, like disclosure of authors and all sources etc.
