Secularism leads to advanced thinking.  Because there is no prescribed teaching, secularists have to use their critical thinking skills to deal with the world around them (whether it's deciding on a cell phone plan or stating an opinion on abortion).  Secular thinkers think "outside the box" in the true sense of the phrase.  

It's absolutely necessary for civilized society! The government can't depend on religious views, the church should be a separate institution. I don't think it's a good idea when you're imposed official beliefs and aren't allowed to decide for yourself.

If you mean getting religion out of politics I am all for it. It's a hot issue in Turkey I guess, since it used to be secular, but is not shifting more and more to an Islam influenced state, right? That is why you post this? Many religions force their rules onto the non believers, and are intolerant against minorities of other convictions. I am very much against that.

I think you know very well what i think about it :P :D

Religion and government should be separated though religion can be a guide for people. I will not explain  much further just to simplify my thoughts I will just say "Everyone should have the freedom to believe what they want to believe."
