He made an ignorant point from a lack of experience, which in, and of itself, is perfectly fine.
Then I made an indisputable point from experience, while he made a stupid point from incredibly faulty logic, and in the face of someone more experienced.
Trying to proportionally shove a female character’s geometry around to fit a rig that’s far too broad in some areas is going to cause really weird bending during certain animations, say, when a character throws a grenade. The shoulder’s verts might become squished all the way towards the armpit. Sure enough, even though, as I type this, I’m rigging a character with 3 layers of clothes on, people will still argue that “oh, it’s just a matter of math.”

sorry lol.
