That makes it a worse argument. How is the fault of Putin and the Russian government also the fault of an innocent Russian gambling site owner who might be against the war? If we see an old Russian lady selling fruit on the sidewalk, should she also be banned from selling fruit? I shake my head at his proposal.
Indeed, as much as possible, we have to be human, don't make an equal judgment on people based on their nationality or skin. When people say stop being racist, we should it's wrong to be a racist, and also sanctioning a gambling site because they are operated in Russia is like being a racist.
That kind of crap is only helping the Russians and their de-Na*ification propaganda. The Russians say they are de-Na*ifying Ukraine. If you go full racist on the innocent Russian people, it will only make the Russians more united against the foreigners. It is definitely not going to help anybody. In fact, it will make the current situation even worse. Seizing the Russian properties in Europe was a big mistake too.
