Proving your critics wrong vs proving your fans right

Fitspo' quotes. Do you love them or hate them? 

I love seeing quotes and memes on social media. Mostly on weight loss or fitness pages. I'm intrigued to see if I can tell what a person's motivations are. I think a lot of people post these quotes and memes to show how positive they are but they probably aren't aware that they are revealing more negativity than they realise.
