I think that perhaps Islam was raised by the OP was because it is another religion that has a blasphemy thing (problem), in that perfectly innocent remarks are sometimes construed as blasphemy. Sometimes they are blasphemous. My point of view is so what? Religions need to get over themselves and their precious gods.
That, btw, is not a slamming of all things religious. It's a slamming of fuss about blasphemy, this making out that blasphemy matters in the big scheme of things.
If a persons' faith is important to them, that's fine by me, but it is not fine for them to think their faith is important to me too, or their religious rules. I don't regard faith as more important or having to have different rules than my spirituality without gods. You cannot insult* my spirituality, so why is religious spirituality sometimes so fragile? That's what I don't get.
* well, you could try, but it won't work. Nothing bruises it. Perhaps some people who have a faith feel the same. If so it's a pity we don't hear their voices more often. Perhaps they could tell fellow religious persons to... um.... stop whining when someone appears to insult their gods. Gods don't need human protection.
