As someone who seriously considered remaining childless, I certainly have no issue with people who are.
however, I think all the posts on here saying, "no of course not, why would I" are a bit disingenuous. There is no doubt that at a societal level, childfree people, women in particular, do tend to have to answer a lot of questions and have judgements made on them. Certainly, when I was musing about whether I really wanted children, you'd think I'd suggested that perhaps I'd turn to devil worship the way some people responded.
I've also overheard the silly, thoughtless comments made to or about childfree people like, "ooh, but she doesn't really understand what tiredness/love/self sacrifice is" which I have a slightly aggressive habit of jumping on, somewhat to the surprise of the person saying it.
And often, childfree people seem to feel the need to preface every comment as if to justify/acknowledge they're not a parent. I had a chat with a childfree colleague today and we were just talking about the craziness of year end and looking forward to the break and she said something like, "I feel completely exhausted and like I can't do any more thinking or creative work but it can't be anything like what you're feeling with children too". Made me sad for her.
