I cant see how something like a tie can cause such a fuss, I dont like this "fashion" of wearing a suit and not wearing a tie, I think if your wearing a jacket then a tie is appropriate, I dont see it as a symbol of oppression.

I have a tie with Saltires on it so it becomes quite the opposite, a symbol of my country, thats why I like Tartan ties they can become a symbol of family and unity.
The reason a tie shows a degree of respect is because its an effort to choose, tie and wear in hot climates so you show your host you have gone to a degree of "trouble" to look smart.

I suppose im old fashioned but I think that ones presentation and appearence speaks volumes about oneself, if I was attending a job interview I would expect to lose marks for not wearing an appropriate outfit.

I recently attended a wedding in England and was suprised to see how little effort some of the guests had made, some of the women wore denim and had tattoos on full display!!! OK people can dress as they like but its a matter of respect.
maybe thats why Kilts are so good-you can wear them on almost any occasion dressed up and down and people ALWAY think youve made and effort!!
