why thank you :o
Dione: I thought I had defeated all those points earlier?! 
Utilitarianism? Don't you think that religious freedom contributes to happiness? Do you think that current laws concerning belief contribute to unhappiness? Again, you are actually arguing on "my" side, yes religious freedom does contribute to happiness, hence why we should actually have religious freedom guaranteed! Currently, we actually don't: whilst we are not as fundamentalist as some other countries, religious views do impact on our laws. Which does not allow for full religious freedom. I am not free to practice what I believe in as the laws in the country which I live has laws regarding for example, fertility treatment that is not influenced by science, evidence or research but by christian ethics.
As for separation of church and state: thankfully our Christian country upholds the rights of all Christian and non Christian people's. Our laws, while not perfect, allow for expression of religious and non religious belief and grants rights to the individual while ensuring that individual religious belief does not curtail the freedoms of others. Again, its not a christian country. No they don't allow rights to non christian people fully, as we cannot escape laws which are based on Christian principles. I can't say: "could I be exempt from that law because I don't support that ethic and think it SHOULD be allowed" they apply to eveyone, Christian or not. Despite the fact that they are based on principles that are relative to Christians but perhaps not Muslims, Hindu's or Sikhs. That means that whilst not individual, a minority religious belief does in fact impact rather a lot on the majority.
Also, the state is not a person, therefore it does not have and is not entitled to a "religion" or a personal belief system in the same way that you or I can. It is there to enable the population to live as freely as possible, and its lack of a religion does in no way inhibit other people from practising theirs, however, if it were to "possess" a religion then that DOES affect people from practicing theirs. For example, if I disagree with the use of contraception due to my belief, I am free to not use any. This in no way affects another member of society. However, if the state also possesses this ethic, and enacts a law that prevents anyone from using contraception, that means no one can use contraception and is forced to live by that set of morals, whether or not they subscribe to it.
Pushydad: The point I'm making is that is does impact on everyone's lives, whether or not you are aware of it, the laws in this country are directly affected by Christian ethics, despite the fact that less than 30% of the country are actually Christian.
