I think the problem, with some views is they become engrained, a bit like religion.
By the way, I don't always see religion as a bad thing. Often having such beliefs can benefit the beholder, for example believing in heaven can make it easier for someone to grieve or when they've just been told they're going to die in a short length of time. As long as having faith doesn't negatively impact on one's every day life or decision making, it's not a bad thing to have.
Full disclosure: I'm not religious myself.
