It has to be a disorder - prepubescent children do not have any sexuality. Getting turned on by innocence is a trait of people in power. That's the reason Elon spends billions on a system to create porn. It's not because he views budding breasts as sexy, but because he has power over normal people. He wants attention, and what better way to get it then by controversy?
Yes. Liking big boobs and staring at big boobs is a virtue or at least more virtuous than the alternative. This is why we need to use genetic engineering to create human women with 4 breasts arranged nicely in 2 racks.
Lady with 2 breasts=Human
Lady with 3 breasts lined up in 1 rack=Witch
Lady with 4 breasts in 2 racks=cow
Lady with 6+ breasts with 2 breasts per rack=pig
