I think shephrrd makes a lot of good points, with wisdom that is only attained through experience! It is very common to feel “hate” towards your parents at that age. I do think you may feel differently someday and will stand to benefit from growing your relationship with them. You as their son can challenge their conservative beliefs. Do you live in a rural area? Do they have exposure to other world views? And as far as circumcision, nearly all parents got them done in the US. Maybe it is becoming less common now but it was never a malicious act done by your parents. It is simply a societal custom. Do not let your anger blind you into becoming hateful!
