It is ok to respect their right to an alternate belief or belief system it is not always appropriate to respect their belief. A widely known example would be terrorism nowhere did she say those who circ are terrorists.
ETA: I do believe there are more appropriate examples but none that those ok with circumcision would accept..
ETA 2 lol: father- assuming you are a male, were someone to take you restrain you and remove part of your anatomy without consulting you how would you feel?.. Would you consider that appropriate? Keeping in mind this is not needed for health but is purely cosmetic. Age shouldn't factor into the most basic of human rights even on an animal we have made illegal most purely cosmetic procedures, our daughters are protected, why are our infant sons still not given that same consideration and protection and why should it be needed from their own parents
