However, debates lead to valuable exchange of information and thus, critical thinking.
Truth is, all that is really happening in a debate, is the opinion is simply the formation of your inner views, whether your pro-life, pro-culture or whatever, and all these disciplines have their reasons and whatnot. So in the end, if you really want to boil it down to the bare facts, then you will see that one side values one aspect of the problem than the other. So, most debates are not debates, but simply a battle of wills.
In this case, its the debate between the pro-choice and pro-sanctity. One side believes that Mecca should develop with disregard to the values that encircle it, the people have no responsibility in maintaining an image (and that can be justified under pretenses) against another side that believes that duty and obligation to a message and way of life are more important.
If you want to dive even deeper, one side wants happiness one way, and the other side wants happiness another way. It really comes down to a personal choice, does more money and choice make you happy (as it does for many) or does a more spiritual presence give you happiness? All a matter of views. Nothing more.
