I've been watching the thread in question and it's annoyed me on several levels. Not enough to say anything because the comments I take issue with are from people who believe they have all the answers and are doing the "fat" people some huge favor by talking down to them about exercise and eating. Idjits.

Weight and weight loss can be incredibly complex issues because our lives are complex. As someone who is establishing an exercise routine to lose weight, I can fully appreciate that it is a luxury a lot of people don't have. Either because of their responsibilities, finances or health. Telling someone "just exercise more" is a lazy way of making themselves feel like they said something helpful when it simply makes them sound like an ass.
