Rationalism is the exact opposite of religious fundamentalism.
What has more merit? To blindly believe something just because your parents do, without question, or to take the time and effort to research the beliefs that you have been told to live your life by.
From the interviews and discussions of Dawkins I have seen , one message I take from him is that 'living a good life is its own reward'.
Much of religion has at its root a fear of dying and the promise that it is possible to cheat death by living according to certain principles. Only your group know the secret to eternal life and only your group have gods favour.
From my experience, fundamentalism seems to be inversely proportional to reasoning ability. So, if a person can cast off generations of traditions and rituals, actually THINK for themselves and base their conclusions on verifiable evidence and then continue to live a good decent life, showing love and respect for their fellow man because they want to, not because they have to, and see the reason and logic for doing so, that, to me speaks well of what man can accomplish.
The alternative is to be a drone, passing your drone blueprint to your offspring ad nauseam.
