I think that if not believing a child born male is worth double that of a child born female, equates to bigotry... I'm probably going to be classed as one, too.
My own religion holds a similar belief in that men and women, boys and girls are separated during services. A married woman has to have her hair covered, lest a man who is not her husband desire her (?!). In the more Orthadox strain, trousers are not allowed to be worn by women at all, and girls are trained (I can't think of another word to describe this, because it goes beyond "teaching" as that usually stops at home, during family time) to be subservient to their father/brother/husband's will.
Although I cover my head (my children can't actually recall the last time they saw my hair), the rest? Bah. I've been slated as being anti- my own religion in the past, because I've questioned why I'm not deemed equal to my brother, or my daughter to my son. I also "married out", so I have that going against me, too (my religion goes down the maternal line).
Whilst "bigot" sounds awful, a horrible thing to be labelled as... you're questioning the inequality of a way of life, at the end of the day. And that is how the world evolves. My 14 year old son has just pointed out, too (as I'm having a quiet little rant about this) that if a sacrifice is made for a child born male, and that child grows up to decide that actually? They're female... do the family demand half the sacrifice back from the charity it goes to?
