Weighing the Issue

Something that annoys me is when people are judgmental of strangers' weight. In online discussions, its common for people to accuse these strangers of being lazy or stupid and not doing anything to try and be healthy. When ever anyone says that there may be a medical issue involved, the judgers snap back that not everyone has a thyroid condition. I just want to point out that you never know where someone else is on their personal journey or what their specific circumstances are. When you see an overweight person shopping for clothes, you don't know whether they have just gone down two sizes thanks to a new diet and exercise regimen. When you see a heavy person on an airplane who keeps munching snacks from their carry-on, you don't know if they are stress eating because they are a nervous flyer. When you see a large person wearing a knee brace and walking with a cane even though they are still young, you don't know whether a medical condition reduced them to unwilling inactivity. I am NOT saying that this is the case with everyone, but I am saying it is the case with SOME people, and you have no way of knowing if it is the case for any given stranger.
To give a personal example, I lost half my baby weight in the week and a half following Baby Girl's birth. You know who also lost weight in that time? Baby Girl. I was exclusively breastfeeding, and there was a very real concern that I was not getting enough fat in my diet for my milk to be as calorically dense as she needed. With a little supplementation (formula for her, ice cream for me) and some pumping to boost my supply, we both gained back the lost weight. While I'm ok with that trade off, and very pleased with our breastfeeding success, you can't just go on a diet willynilly while breastfeeding, so I'm still closer to my end of pregnancy weight than my wedding day weight. Meanwhile, some more appearance-conscious women I know who weaned earlier or didn't breastfeed at all did do the diet and exercise thing and look like (I know better than to ask a woman's weight!) they have returned to their prepregnancy sizes.
That said, I'm thinking if I don't read as much from online advice columns and their accompanying discussions, I won't come across as many people being judgmental of every behavior under the sun. Since I strive to not be judgmental of others for their own choices and situations, I'm going to cut down and see fewer examples of this behavior. I don't think it's judging to be able to tell when something is rude or hurtful.
