You know, it may be wishful thinking, but I honestly don't think this is true outside the IG/tumblr HAES fat acceptance echo chamber. Most fatfucks I personally know in the diabetes Mecca of Texas still seem to have some amount of shame. There are always the "IDGAF" scootypuff jockeys that are insane but I see the look of shame in most piggy eyes when I subtly shitlord. YMMV, of course, and I've always generally been ask optimist.
