Also, if governments had done their job and prevented all travel to/from China (as well as all countries that refused to implement similar restrictions) in the beginning, then we likely wouldn’t be dealing with a pandemic right now, and people wouldn’t have been discriminated against (more than usual that is). I’d say in the beginning (not anymore) it was also justified to be wary of anyone believed to be Chinese since there was a high chance that they recently been to China or had close contact with someone who had been (since Chinese tend to stay together when abroad).
