You asked how anyone could ever perceive Fi as selfish. I tried to explain that sometimes it can appear this way from the Ti+Fe perspective.
You said that you had plenty of Fe, but also didn't understand how Fi could ever be perceived as selfish. I said this seemed odd given that someone proficient in Fe should easily be able to see why Ti+Fe people might find Fi selfish, even if they're wrong in this assessment.
You then veered off topic to inform me that selfishness and altruism exist. I don't see the relevance.
