I completely agree with the idea of 'polyfuckery' being a derogatory term; even aesthetically I find it harsh. I like the fluidity of the concepts and understand definitions may be a little different depending on who you're talking to. I am still trying to figure out where the term "flexible poly" came from and if there is a countering term like "rigid poly" (or something) that means the opposite...
Love many things, for therein lies the true strength, and whosoever loves much performs much, and can accomplish much, and what is done in love is done well.
