It already does offend them. Ever see the look one of those behemoths will give an attractive girl in a bikini? Or the look of distaste a bloated male mayonnaise chugger will give toward a fit guy in runnin  207  g shorts? They already come up and say shit like "you need to eat a hamburger," or some such drivel. They'd rather see us assimilate into fat culture so they have more to hugbox and play victim with them.
