If they are home they should act like they’re home, same for anyone. If you don’t like where you are and associate with another country...go there. These melting pots do not work, history has proven it. You either embrace your new country and fully assimilate to it’s law and culture or you beat it.
These Ukraine citizens of Russian ancestry are being persecuted by the current Kiev strongmen that took over the country. They have no legitimacy to do what they are doing, and are guilty of international war crimes for launching military strikes against Ukraine citizens.
The Administration they replaced came to power as a result of a nationwide election, not a violent overthrow of just one city. That previous Admin did not launch military attacks, yet they were “oppressive”. This new gang leader has cobbled together a mercenary force of foreign and domestic fighters and set them on the country’s citizens. This is progress?
At this rate there will be Russian tanks in Kiev by Easter, I guess this is what you want.
