AITA for telling my DIL she wasn’t invited due to her weight

Have you ever read the “Am I The Asshole” questions on Reddit? If you don’t know what AITA is: People ask the internet if they were in the right or wrong about a situation that happened in their life. Well, these questions are a source of endless entertainment for me! I brought my friend Summer Innanen from Eat The Rules podcast to get her verdict on four AITA posts that I picked out around weight and diets. Some of these AITA question askers are grade A donkeys and also there are some grey areas where things are less clear. TW: anti-fatness, ableism, gender A-Hole behaviour.
