Lizzie, I said that my DH gets coffee breaks and has lunches with colleagues. I know not everyone does. I worked in a very high-pressure job as recently as Feb this year, and I, too, ate lunches hunched over my desk preparing for my next meeting or sorting out household admin and, for me, that was still easier in a lot of ways than attempting to get some food in to myself during a "family lunch".
No one is saying that working with kids isn't bloody hard (I know from personal experience that it is really, really difficult). But it's ridiculous to imply that SAHP are living a life of leisure.
No, I don't wash using a mangle, but loading the machine is the easy part. I'm still sorting, ironing, folding and putting away for four people and that takes time. As for pets - do you have any? I do the cat's litter, walk the dog, groom both a bit every day at this time of year as they're losing winter coats, feed both twice a day, and go to vet's appointments. None of which are huge jobs, but they are the little jobs that add up and mean that even when the kids are having down time, I am fully scheduled.
Yes, I get that working parents have it rough, but SAHP isn't all soft-focus and MN either...
