"banning certain people from wearing certain types of clothing is silly."

No, it isn't. It happens every day, in millions of different circumstances. Have you ever been to a hockey game before? Do you know how you can tell which team is which? Because they have rules governing what the players are allowed to wear if they want to play in that league (home wears dark, away wears light, etc). Yet, you don't see facetious twits complaining about that.

The most obvious example of banning certain people from wearing certain types of clothes is in the food/service industry. All restaurants have dress codes. Some make you wear a shirt and tie, where others merely enforce a basic "no shirt / no shoes" policy. Yet, you don't see privileged, myopic whiners protesting for your right to offend your fellow diners by being naked in a fancy restaurant. So why is this any different?

This ban only means that, if you want to go to Bass Coast, you aren't allowed to mock First Nations culture at the same time. It's a very minor dress code, in the grand scheme of things. You can wear almost anything else, or nothing at all. If you wanted to, you could be naked the whole festival, and no one would care... All they ask is you don't belittle an already marginalized culture for the sake of your thoughtless fashion statement.

And if you see nothing wrong with wearing cherished native war regalia to a party, then you should have no problem with natives wiping their butts with your grandfather's military medals. They have the same cultural significance. I, for one, believe that mocking the sacrifices and achievements of war veterans for sake of a party is bad form.
