I agree with you, I don't think anyone should silence the President of the US and I am very aware of the fact that Americans couldn't do the same in other countries.

I just don't think it's healthy for us to dismiss a whole group of people based on the actions of one person (after all that's what the left does to us too, we should ride above that). The action itself should be the problem, not necessarily her background. And if it's a larger problem (like China with the CCP) with a foreign government or group, we should call out that group's (and the individuals a part of it) for their actions, not because of their ethnicity.
