yes,it does matter. we are fortunate in relatively enlightened europe that such fundamental views are rare and dealt with - usually - appropriately (or dismissed as barmy) however,in other parts of the world such as in the us and the middle east they are strongly held views that often lead to the persecution of the other, different (inferior) religious and cultural groups. of course, there are many millions of good people who would never wish to do anyone any harm but there are many others who will support the views of powerful religious leaders (always men, by the way) and be directed to persecute other groups.
in the uk we have some religious schools which divide children from an early age. cant we leave children the world over to make their own minds up when old enough to decide what makes sense to them? by then they should realise that we are all just paople -some good, some not so...and aggression between us is perverse and childish.
