...Yes! Clearly!
That would be ridiculous. Obviously. I mean, why would fat dudes even do that? Ha ha ha ha... ha ha. Ha.
[whispering] Drop the thermostat another 2 degrees in zone 4-1831A/N and put 5% more cellulose powder in the cafeteria meatloaf.

This sounds to me like yet another form of tribalism. I get that people may become annoyed when the world appears to be shifting its loyalties away from their tribe towards someone else's, but no good will come of deciding that the skinnies and the fatties are natural enemies, and are responsible for the others' ills.
EDIT: Actually, clothes that fit could be hard. I wasn't terribly round, I ended up with a 38" waist at my fattest at 5' 10", but usually around a 36" waist. But my legs, thighs in particular, were not toned or thin. My option on pants almost always required me to go up several inches on the waist to get pants with large enough legs for me. My thighs, now, are well-muscled and toned, but I still have a hard time finding pants that fit them well now that I'm down to a 32" waist.
But I still don't think the problem is catering to the obese hurting the skinny. The problem is that being that thin is abnormal (from a statistical perspective). Consequently, it's a small market. It's hard to justify making off-the-rack shirts that fit a 6'2" 120lb man. Just as it's hard to justify making of-the-rack shirts that fit a 5'4" 250lb man.
So the obese are oppressing the skinny? First I've heard of this. Please, tell me more.
