Because we can see characters get hit with the ugly bat wherever that ideology takes root. Seriously compare the asari in ME:A to the mass effects before. Asari show themselves as an idealized vision of what a being wants so apparently ryder is into ugly or more likely it was a concious decision due to the same idiocy that made them hit default fem ryder with the ugly bat. It's amazing when we can make crazy realistic characters based off facial mapping that people claim there wasn't a concious effort made to make jayde freaking rossi ugly.
