I love blog posts about religion. I love hearing people proclaim from the digital rooftops how they've found Jesus, backing up their faith with arguments based entirely on emotion. I love hearing people foam at the mouth over how terribly evil all religion is. I don't much care what you believe, just so long as it places arbitrary restrictions on other people, you're closed-minded, and are dishonest in your beliefs. You see,

Joking aside, I have to agree with you Iain. I myself am supposed to be a muslim but don't really practice my faith. However, that does not mean I still can't learn a lesson or two from the ethics Islam, or any other religions teach. They are mostly healthy and are designed to be for the user's good.
I believe everyone, religious or not should at least study the teachings of a religion because at the core a religion is just a way to make people do the right thing. It has been veiled by this black cloth of doom called 'bias', but those smart enough to see past that cloth are the real winners. :)
And hey, if there really is a 'God', everything would be so much easier. It doesn't mean you have to preach his teachings or worship him at all. He's just a good way to blame things on nowadays. He's also a good explanation for the most complex problems of the universe. If only we could somehow harness his power. :d
Honestly though, if there is a god, he is not at all spiteful or full of revenge. If he was that narrow-minded things would be a lot different.

But in spite of that, these are my thoughts on the subject matter: as human beings we are opinionated, and we want to find congruency between our opinions and those of people we care about. More so, things that are deeply integrated into our daily lives, such as religion for religious people, or politics for politicians. Therefore it should not come as a surprise that the people who care about you want you to be not only honest, but open about these things. To consider the opposite point of view: wouldn't you want to know, if the person you were dating was racist? Even if she is the most respectful and honest person in the world, I would feel betrayed if I one day found out my girlfriend is racist, regardless of whether she hid it or simply did not 'openly say it'. To many people (the girl you dated included), religion carries a lot of weight, if not as much as racism, and I don't think this should come as a surprise.
This, of course, does not stand when discussing people that you have no relation to, and that you do not want to have a relationship with. I think there's nothing wrong, and even something moral, about not expressing one's more disagreeable opinions (such as atheism or theism are) in public, without context. It also does not stand when you express a desire to not state your opinion, which is something others should respect -- however this is irrelevant to you because you are, as you said, honest about religion, or at least religious orientation. [edit: apparently you aren't and I misread]
