Supertaster!
Really?!? Huh. News to me.
In some areas, saying someone is childless is equivalent to saying that there is something physically wrong with them.
People who prefer child-free want others to know that it is a choice, rather than fate
Exactly.
But “child-free” makes children sound like an infliction. While there are some days, usually they’re not.
We need a better term, but I’m not smart enough to figure that one out.
Nulliparous?
Well, it is neutral. 
Some people can’t have children (at least their own). Others choose not to. Either way, they’re childless.
If you’re going to enjoy all the benefits of being without kids, then you can grow a thicker skin about what we call you.
And you should get used to, “breeder,” right?
There are both benefits and disadvantages to being without children; as is true for many other possibilities in life.
I would have used a neutral term if I’d been able to think of one. Both “childless” and “childfree” seem to me to imply criticism.
Which is the correct choice for any given individual depends on that person’s nature and circumstances; and is in any case, as has been pointed out, not always a choice at all. Or sometimes a semi-choice: I chose, not to not have children at all, but not to have children without a long-term reliable partner who would help care for them. I never found such a person (that is, I know a number of them, but they’re all otherwise partnered and/or at least one of us was otherwise not interested in doing so with each other.)
This is correct.
I could laugh it off quite easily.
I guess I just don’t see any stigma in being child free. No criticism intended or implied, at least from me.
The stigma, I think, is not on the person who is child free, but on the implication that the person who does have children is thereby made unfree: some people think it’s meant to imply that it’s much better, in general, not to have children.
ETA: Having children does of course limit one’s other choices; but there are all sort of choices in life that limit one’s other choices. It’s hard for me to think of something that doesn’t.
A lot of people do fully intend that criticism. It just gets very old and tiresome. Like an old joke that some people just have to keep repeating.
I’m curious about the bathing poll. Is skipping two days the same as bathing every other day? Because shortly after I retired, our drought got very bad, and, as a good citizen, I started showering every other day. Unless I was really stinky and going someplace.
I currently bathe when I think I need it. Which mostly means after I exercise. Exercising enough to want to shower afterwards is something I do 1-3 days each week. (And sometimes twice a day when I go to dance weekends.) I enjoy being in the shower, but I dislike both getting into the shower and being wet afterwards, so I’m not inclined to take more showers than I “need” to maintain my desired level of cleanliness.
I also don’t wash my shirts until I smell myself when I put in on, or it’s damp when I take it off. When I catch a whiff of myself, the shirt goes off again and into the hamper, and I pull out a clean shirt. I have a pretty good sense of smell. This method wouldn’t work for my husband, but I think it’s okay for me.
You can all call me stinky. 
I hope I’m right that it’s okay.
I can take a very quick shower, but I’m not skipping a day. I’m also not going to a dermatologist; my single experience with one was awful.
I have not consulted with a dermatologist; but I know how my skin feels, and how much skin cream it takes to keep it from cracking and itching. I usually bathe/shower about every three or four days, and still go through containers of skin cream at some speed. If I’ve done something unusually grubby (and I do usually do some things some other people think of as grubby), or if I’m going to be in close quarters with other people at a meeting or the doctor’s or something, then I’ll take an extra if the timing didn’t work out right.
If I go longer than three or four days, my head starts to get itchy and I start to smell myself; so I’d rather not go longer than that.
I have asked people who I can trust to tell me whether I stink. They say that I don’t. I suspect that most people don’t need to shower as often as they think they do; but people of course vary considerably, and some might need to – plus which, as long as there’s enough water, people should be able to shower when they feel like it.
My daughter was told not to take too many baths as a kid, due to her skin. She stank for a few years when she was an adolescent, but she doesn’t stink now. Well, maybe a day every couple of weeks she does, but not usually. And she still doesn’t shower very often.
See, I’m your opposite. When my gf has me put lotion on her back, I then scrub my hands with harsh soap to degrease. Some people need moisturizer, while I’m too moist.
I couldn’t decide if my neighborhood is middle class or lower middle class. It’s a neighborhood of small, mid-century ranch houses, but the yards are actually fairly big by the standards of this area (albeit small compared to what I had as a kid growing up in a rural subdivision). Not that the yards are huge, but the newer houses around here come with backyards just barely big enough for a patio and not much else. And being an older, more modest neighborhood in an otherwise fairly affluent town, I wouldn’t be surprised if the people who lived in the snootier neighborhoods looked down on this area. But on the other hand, with home prices in California what they are you have to have a fairly decent income to have a house even in this neighborhood (but it’s nowhere near as bad as the Bay Area). But I went with lower middle class just based on comparison with the other parts of town.
