You write: "She is complaining about his general defense of immigrants and refugees"

Actually, she is not complaining about that at all. She is complaining about whether the state's or government's PRIMARY duty is to look after population or to look after other countries' population, and, whether charity is the government's duty or the individual's citizen's duty.  These are valid questions. Could you point out where the 'hate' in all of this, that you so passionately refer to? :)
