With respect, op, your statement is a gross generalisation, and simplifies the situation, by saying people blindly accept laws. I think people perhaps lack knowledge or are confused by the complexities of why and how laws exist. Most people just want to live honest lives and see laws as being there to protect them, I would agree with them, in the main.
Laws passed in this country are based on a number of factors. As we are in a democracy Public Opinion, culture and perceptions are used to inform law making decisions. It is a long drawn out process that can take 5, 10 years sometimes a generation to get through parliament. Law makers are constantly assessing Public Opinion - this is made even more challenging because people's beliefs evolve and shift like techtonic plates (what is right, what is wrong) and can be influenced by many factors such as their upbringing and the "globalised " nature of the world around them. By that I mean that people have more ready access than ever before to see what happens in other parts of the world (media, internet, modern technology) and this can influence their thinking. For example people have become increasingly aware that Sharia Law in its extreme is not a good thing and therefore do not want that in their country. Then in addition, you can overlay onto those factors the electoral system, changing governments, what each government can hope to achieve in their relatively short term of office.
Governments try to gauge public opinion as best they can, but they cant just go ahead and pass laws, there are several additional hoops they have to jump through. For example The House of Lords - made up of Seniors with a wealth of experience behind them - use that knowledge to (by and large) predict whether a law is correctly focussed and likely to be enforceable. We know that this is an incredibly difficult thing to get right every time!
My point is that most people are as far removed from law making as you can possibly get, it doesnt mean they blindly accept, they are law abiding citizens! They have a vote as a democratic member of the political 'system'and trust that the government they elect, will manage the country wisely and well.
It isnt a perfect system, but its all we have and hey, when considering the alternatives, its probably the best we're gonna get!
