What's he getting at is that the genderswap should reflect their original form. I.e. a fatass should still be a fatass, see example. If the design doesn't capture the spirit of the original character and is just a hot girl with their clothes, it's more cosplay than genderswap, which is what a lot of these are.
For the record, I'm not that guy, and I have no horse in this race. Good art is good art.
