Why are so many people so close-minded?

The more I research, the more I read, the more I learn, the MORE I really want to have a natural childbirth. But, EVERY time I try to talk about it with someone they tell me I'm crazy, I am being "brain washed" or I am just naive because I haven't given birth before."  When really I think THEY are the brainwashed ones... 
It's just SO frustrating to have ZERO support and have people think I'm crazy and an idiot for believing what I want is the best thing and the right thing.
