Nah. It's a collared black and yellow shirt with a double headed eagle on it. Too many red flags and we live in fascist times, so I'd rather wear value-neutral clothing so no one can read much into me. Grey man, except without the operator worship. I'm not wearing all black with a red bandana either.

Granted, if I am watching an AEK game or even in a Greece, I won't hesitate to wear it. But that's a different context.

OK sign is a little different because it was a trolling effort that the left took it seriously. Also that's such a broadly known symbol that you kind of have to be keyed into it, and using it actually saying "ok" is pretty clear. It's mostly just a trolling in photos thing.
