Just for the record, every post of yours I can remember has been pretty reasonable and balanced.
INFPs, like every type, run the gamut from balanced and insightful to paranoid and bat shit crazy. The crazy ones just tend to go really far off the deep end with their anti-typology rants.
The boxes aren't prisons because they can be molded and rearranged to fit one's personal idiosyncracies. The boxes don't really even say much about anyone's opinions on specific issues; they just describe the way people build their worldviews and perspectives. That leaves infinite room for a variety of perspectives within every type.
If you think typology labels box you in too much, you probably don't understand the nature of typology labels very well.
