Are we to politically correct or just over sensitive?

[Kendo]

I see no problem with the shirt, but of course people will interpret it in their own way.
There is nothing wrong with National pride, patriotism is not racism.
There is nothing wrong with pride in our flag, many servicemen have died serving it.

In my view, if you wish to come to Australia and enjoy the wonderful life we have the good fortune to live, then welcome aboard.
If you wish to come to Australia for any other reason, then don't.
If you are currently here for any other reason, then leave.

Politcal correctness has gone mad, it should leave too.
