The Queen is only the head of power because of birth. And if she had an older or younger brother then he would have taken the crown.

It's a title handed down by preference to the next male in line. The only reason Elizabeth got the title is because her Uncle abdicated the crown and only herself and her sister were left, if her Uncle had kept the Crown, and had son, it would have gone to them.

How in hell you can argue that England favours women because the Queen (by an accident of birth) is the Head in an institution that is hereditary based on the male line, it hurts my head!
