This morning I heard a protestor at the inauguration being interviewed and she said that she was there because we all come from immigrants and that none of us would be here if not for immigrants.

First of all, I have no idea what she is protesting. I don't know of anyone who is in favor of stopping immigration.

Secondly, why aren't these people celebrating the first non US born first lady since 1825?

Donald Trump is married to a first generation immigrant. How can anyone think that he is anti immigrant?
