I may have misread, but I'm not sure anyone has been asking you about nudity - I know I certainly haven't. What I have done is refute some of the things you've said about nudity not being allowed in certain places. As I have said repeatedly it IS ALLOWED, so in comparison, a brief glimpse of a nipple is no issue whatsoever.
Similarly, nobody has been arguing that everybody should walk around naked all the time. I believe people should be free to wear, or not wear, whatever they want (safety issues aside), whether that be a woman in trousers, a man in a dress, bikinis on the beach what an impractical invention that was or being nude. It really doesn't matter, and if you don't like what someone looks like, don't look. It really is very simple.
As for hygiene, there are some occasions when it is more hygienic to wear clothes (eg when menstruating) and some occasions when it is more hygienic not to wear clothes (eg when swimming or in a sauna). Again, if you had read previous posts, you would see that whilst I said that clothes are generally not needed (sorry for the repetition, warmth and safety aside) many people choose to wear clothes, but this is because of social constructs (which you agree with) not because they are needed. There are clothes that are pretty or soft or sexy or professional or fashionable or any other reasons why people like particular clothes. Doesn't mean they are needed in the true sense of the word.
And you keep saying you are scared of men's sexuality. Have you had a personal bad experience, because you seem to have such a low opinion of men? Sexual violence, sexual aggression, sexual harassment is against the law, whether nude or otherwise. Naked men walking around with erections just does not happen with simple non-sexual nudity. Being amongst other naturists is a very safe place to be.
Sorry for the essay, but felt I needed to clear up a few things. Getting back to breastfeeding, full nudity in public is NOT illegal in the UK, so a glimpse of breast or so what if a mother did entirely remove their top half is not a problem, and certainly not something to get your knickers in a twist over.
