Overweight people are worthy of, and capable of, finding love. I know your comment is in jest but it also propagates negativity in a way that is corrosive to others’ self-worth.
For those who read your comment and feel bad that the humorous angle is reality to them… it isn’t. Don’t let the world make you feel bad about yourself.
For those who read it and get a chuckle about fat people… your world view may benefit from some compassionate adjustment.
