Maritsa's egregious misrepresentations of Fe and Fi are simply too "off the mark" to point out every instance where they stray from the actual functions. It's simpler to point out a more correct understanding.
As Aiss pointed out, any "newbie" should be wary of Maritsa. She practices her own convoluted idealized version of Socionics, widely rejected by virtually everyone on this forum. One may read what she writes, but this must be held in the context that what she says carries virtually no weight regarding Socionics and should not be mixed with an actual understanding of the theory.
