Not all opinions have equal weight!
A devout Muslim might be of the opinion that the female form should be covered at all times to protect the gaze of any men who pass her by. A devout Christian might be of the opinion that two men cannot engage in a sexual relationship. Indeed it was once popular opinion that people of a none white colour could be sold as slaves, but it soon gave way to a new overpowering opinion.
But as a society, we try to encourage personal freedom and choice. So long as those choices harm nobody else. Therefore, if a 22 year old woman chooses to marry a 52 year old man, it is her choice and must be adhered to.
