You may think of this as a joke, but genitalifying is a thing already, that is where you base sexual attraction solely on the genitals someone has, and that is of course seen as a mortal sin too. As is being fatphobic. It already was for judging people just for social stuff, but it also no longer a good thing if used for sexual attraction.  In other words, if Fat Albert is a mate and comes down the block and I like petite blonde girls, Fat Albert gives me the look and tells me we need to get down sucking eachothers dicks, it is wrong for me to say no if I like the guy socially.  God I wish I were joking.
