If a man will make a law then what benefits he gets from advising you as not to drink wine and not to have sex out of marriage, why he needs to ask you to fast for a month ...etc.
Actually many things in religion is hard to follow, for example some would be happy to drink wine and if religion prevent him from doing so then he won't be glad to follow, what I mean if a person is making such laws then it is better to make laws that make people happy such as drink wine if you wish, make love with any girl that you love, enjoy your life and eat all kinds of foods you wish...etc
