She should be upset at Humas is the point. I know you don't understand that because you support them, but the hatred and anger should be pointed at them.
Also, she is a sitting member in the congress for the UNITED STATES OF AMERICA. It is sad and terrible if she does in fact have family over in Palestine, but again, she should put her energy and efforts towards getting Humas eradicated and her family out of there...not hating on one of the biggest allies of the country she was elected to support and defend.
