OP, I agree with the other posts that say the thread title is perhaps inflammatory.
I guess I'll just start over and say this:
--I don't think it's okay to judge individuals. You usually don't know their situation, such as in this case. Sometimes it's hard and we judge anyway, as evidenced by the millions of MDC posts about SILs or MILs who love sleep training and formula, who would never nurse because their breasts are for their husbands, and had elective c-sections so they could "stay tight down there". I think the rolleyes face was made for these posts.
--I think it's totally fine to judge foods and their quality, regardless of whether others eat them or not, and whether they feel defensive that you would not eat some of the same foods they eat.
--I think it's fine to judge a society by what food it finds acceptable. I do this with the fact that our society accepts formula and bottle feeding as a default (regardless of individual situations, some of which warrant formula feeding), and continues the trend of artificial junk throughout the rest of people's lives. To me the situations are parallel, but the humans are older. In the same way mamas rail against default formula feeding I rail against feeding children after they are weaned the same oils, sugars, flavors, dried milk, synthetic vitamins, preservatives, etc. found in formulas. I think the default food given to children in our society is sad. Sometimes it's warranted (like formula is) for health and economic reasons but for the most part it's just the unexamined default. As a society that we've been misled and removed from our nature (like formula companies do to us) by being told we should eat these foods. And I'm not apologetic about feeling that way, although I would never say that aloud to anyone whose situation I didn't know well.
So, IMO, since you asked, I do think you're being judgemental. Judge the food and the society, but not this particular mama. It's not snobby or judgmental to think this food is junk. The phrase "junk food" has become so overused it fails to register anymore. And I'll throw in my unsolicited advice to not say things to people because as you've seen (even before I chimed in earlier) people can get quite defensive about food.
