My first instinct is to answer, "Of course not!", but then I have to take a second and say to myself, "I was raised in a society that does this, and therefore that teaches people to do this, so I probably do this, too, at least sometimes."

Exactly, that is why implicit questions are preferred in these types of questionnaires to minimize the suggestibility of the items. To avoid this type of response bias, the respondents are usually asked to rate their own daily behaviour, or specific—rather than generalized—judgements they might hold. The items are usually not formulated in the second-person form, as this comes across evaluative. These things said, I feel like this questionnaire is not intended for screening the general public but aims to foster self-criticism in our rather unsizable circle so I think none of my remarks above really apply here ^.^

The page history is full of vandalizing edits, mostly 'an'caps it seems, loling at their tactics.

I think their sentiments as such don't prove their point wrong but rather its their position. Active self-criticism is one of the most crucial virtues revolutionary politics can have, but when you idealize your politics so much that it doesn't correspond to any real practice in the world, that might be moving away from criticism and towards embracing excuses that ultimately bring on apathy which limits the social and theoretical capital of these revolutionary movements. If you are not glad with how some people are doing some things, why don't you do it the way you see should be done? You can build your own praxis if you want to show an alternative.
