I haven’t read every post here… I read the first post and it seems like there is a dispite on whether taking “tznius too far” is a bad thing, good thing, neutral but if the tzibur wants it then who has any right to complain… something along those lines.
I don’t want to comment on the specific case in the OP, but theoretically, in a very similar case but it was a picture of a 4 year old boy in camp wearing shorts that was blurred out in the name of tznius, would people have the same reaction? I mean, if the tzibur felt that a young boy’s legs should not be shown in a public magazine, would this be an appropriate expression of tznius?
IMHO, people can do what they want. If there is a consensus (but I mean a real consensus, not social peer pressure), to blur out pictures of boys and girls who’s pants or skirts are “too short” that’s fine. But I think it’s hard to call blurring a picture of a little boy for wearing shorts “tznius,” “halacha” or a “chumra”. So too, just because people want certain pictures blurred out of a magazine, and they have every right to do so… that doesn’t automatically make it an expression of tznius, halacha, or a chumra.
