I disagree with you.

If someone is wearing a Boston Bruins jersey in public, I think it's reasonable to believe that they're a fan of the Boston Bruins hockey team. I _could_ ask them if that's the case, or if they're a New York Rangers fan that's wearing it ironically, but that would (probably) be wasted effort, because I have a good idea of the answer I'm going to get.

It seems reasonably straightforward to apply that to other team insignia, especially one that is so clearly affiliated with a specific political leader, and their political outlook.
