Hmmm. Being supposedly self-contradictory is the equivalent of being immature?
The statements:
"No one is ever really broken and we don't need fixing"
"most human activities" are not integral—they are instead partial, often fragmented, frequently broken."
... are not contradictory. The first deals with the individual and the second deals with the activities in which the individual partakes. Different levels. Not very good argumentation here.
As a spokesperson for the approach you are espousing, you are failing miserably at being logically and emotionally persuasive.
