For a start the man you mentioned who got robbed in the Josh Taylor fight is also European. He's just south of the Border. Catterall is also a good fighter. Taylor, as much shite as he spouts out the ring has had some great performances in the ring against non euro fighters at the top level. Can't write a fighter off after one loss.

Eastern Europe is still Europe, Bivols mum or her mum might have been born in Korean but if, just like GGG has Korean/Russian roots due to the influzx xof Koreans over to Eastern Europe during the Russian empire well over a century ago. He also but classes himself as a kazakh like Bivol is from Kyrgyzstan making him European like Usyk, Loma, Klitschko etc.

If your going to bring heritage into it then fuck knows what all these American boxers are going to class themselves as. One day of the week they decide they're Scottish, then part Irish then part Italian too then obviously the African ones.
