I get that too. "Real Women" come in all structures not just curvy!
I have been a woman for a long time now & I've been thin & fat & in between - but I was still real!

I think we are running the risk in society of normalising obesity so as to remain as PC as possible also. Obesity for most of us doesn't feel good. It isn't good for our health, our self esteems or our emotions. However, labelling folk as either skinny or fat by others is thoughtless. For both "names" potentially can cause pain.
