No you are making an assumption based on your preconceived notions of what you think an Australian Croat would do...
Not trying to get personal but you mentioned having Croatian ancestry, would that make YOU referee a Serbian founded team differently? Or stop your or your kids playing for one, or even, heaven forbid, supporting one if your kids or grandkids played there?
We aren't int eh 1980s anymore mate... I get Robbos point of view and yours that you dont relate to these clubs, fine... but you can't state with a straight face that the people who already do don't exist, I am friends with some of them and see them every week.....
