anarchism is a system. some anarchisms emphasize individuals (or "the individual" as a category), and some don't.
all unfair standards would surely not "be abolished," at least in my vision of anarchy, mostly because "unfair" is so entirely open to interpretation, but also because there wouldn't be any "abolishing," there would just be no social structures that were so overwhelming that people who were unhappy couldn't avoid them.
what do you mean by "human nature"? especially when you put the term in quotation marks?
i don't know what you mean by majoritarianism. perhaps you could give an example of it?
