It’s a perfectly normal reaction to be repulsed by extreme self centeredness, which is what this “my body, my choice” crap is. The people who have the airline or train seats they paid for encroached upon don’t get to choose.  The nurses who injure their backs trying to move these behemoths don’t get to choose. The airline pilots who have to recalculate takeoff or landing “on the fly” because of the extra adipose don’t get to choose. The people trying to catch trains or move somewhere quickly only to have their path blocked by a lumbering obeast don’t get to choose.  But don’t expect a salty, triggered fatty to consider anyone else’s feels, comfort or safety, except their own.
