What a bizzare assumption that I'm being deliberately obtuse.
I missed that kids in your area are in 4 inch heels. I've never seen a little kid in heels that tall. Maybe it's a regional thing.
My posts were in response to people developing dyspepsia over a 5 or 6 year old wearing a fancy dress, hair and heels for her graduation. I just don't think really little kids wearing any kind of clothes makes people swear or stop using silverware. Your experience seems very different.
My kids choose not to wear anything they can't climb in and prefer to be barefoot over any type of shoe. They choose not to wear most characters or shirts with words on them. I talk about my feelings about clothes and why I dress the way I do.
If they spend a couple years in glittery shoes, I'll be okay with it. And I enjoy their friends that dress differently.
When people have no sense of what is and is not appropriate, then, yes, you will see a breakdown of social niceties. If someone doesn't know any better than to take their child (and themselves) out in public in stripper clothing, they probably are clueless about how to act in polite society.
Why do you think businesses have dress codes? When I worked for a large corporation, it was the woman who would wear overalls and a tube top to work who also got in trouble for using inappropriate language all the time. Coincidence? If you care enough to dress professionally, odds are you conduct yourself as a professional. There is a relationship.
YMMV, but I haven't seen anything to convince me otherwise.
