Every muslim country that made religion there law has made a example of this whole thing. If you look at today's religion, even in our country. They always want everything to be done there way, a more primitive way. Can you imagine what western countries would be like today if lead by Catholic Laws? Birth Control would be illegal, hell maybe even condoms? Everybody would be afraid to not celebrate christmas, even if they were from another religion as if a religion dominates the law. You really think theres room for other religions? Nope, to a religous person there is only one true religion, theres. As you can see in muslim countries, that are dominated by religion laws. Everybody is Islamic, and has to follow the Islam rules other-wise they get punished. You will find very little room there for Muslims to adopt another religion, infact its against there laws.
In Canada, and other western countries. By having a non-religous laws, everybody can have the freedom of choice to choose the religion they feel they belong to without having the RCMP coming to your door going, "You are not celebrating christmas, you know that is against the law. You are going to jail"
Sharia has done a shit job ruling Muslim countries, for example. Just look at any muslim country that is religion dominated. I don't see how it would work being in our country, if it doesn't even work there. If Muslims get there own religious rules, then the Catholics will demand there own, and so forth. Just what we need, to go back to the Medieval Ages where religion was the law. What a great time that was .
