Do you think there's any possibility, in all honesty, that you actually haven't truly understood what secular really means? You seem to want to have it both ways. NOBODY is accusing you of being theocratic - actually, I've gone out of my way to say I don't think you're that at all.
Secularity removes religion from the state. This does NOT mean religion or religious practices are banned, but it makes the state neutral in these matters. So everyone is given the same rights as everyone else - the government does not play favourites, and treats the non-religious with the same equanimity as the religious. Hinduism and Islam (for example) have the same rights as Christians. No one religion gets precedence over any other when it comes to representation in Parliament, for example (as is the case currently).
It's about equality.
By saying that it goes against your Christian beliefs, you're saying that equality with others is not Christian. Really? Is that honestly what you think?
I have faith in God because of the person who is Jesus Christ. Now he lived on earth 2000 years ago Did he? Without resorting to hearsay, can you prove that?
So I suppose it does take blind faith for me to read about it and believe it happened from the Bible. If that is blind faith then yes, I have used blind faith to come to a position of belief Fair enough - but you cannot then take issue with me for raising my eyebrows when you claim your faith is based on "critical thinking".
The bridge is made of the evidence as presented in the Bible and in wider readings and in common sense (by this I mean, there is no real plausible explanation for how come Christianity got started if you don't believe that Jesus rose from the dead, there's no easy way to explain how a religion with a murdered leader went on to spread like wildfire across the world unless the tales were true, human nature would dictate that if your leader of your wacky new cult Christianity got murdered before your very eyes you would give it up sharpish in the face of hostile Jews/Romans etc)
The Bible is a book - words on a page. It was written by people who were already part of the cult - so not unbiased, impartial observers. Therefore, on it's own, it's not actually evidence of anything.
Your religion is one of over 10,000 that have existed through human history. They all got started with some myth that got bigger and bigger and bigger. That's what Christianity did, and it collected rather a lot of important people as followers along the way - people with the power to kill and persecute those who didn't adhere to the faith they favoured.
Christianity did not spread like wildfire around the world. And if your only defence is "Why would so many people believe it if it wasn't true" then kindly explain how so many people believe in Hinduism and Islam? They can't be true if yours is.
