Making life for Russians a bit more uncomfortable is fine. However one should not use this as an excuse to begin a general witch hunt. We have been there before. Japanese Americans during WW2 did what they could to show support for the US but still got put in internment camps and their houses and businesses stolen. In my native Norway half-German kids suffered through their whole life for the crimes of their fathers.

You don’t fight an evil by emulating it. Inconveniences are fine. Make them wake up. A witch hunt is NOT fine. Those Russians being brave and standing up to Putin need our support.
