Atheist vs Anti-theist

[robvalue]

I'd be interested to know how people's answers would change in the following scenario:

Imagine religion still exists, but it somehow does no harm anymore, in any real way. Obviously it still involves some irrational thinking to believe in it, but it's not been forced on anyone anymore (especially children) and any other negative factor you can think of has been neutralised. It's a secular masterpiece.

Would you still consider yourself "against" religion (further to it being irrational) and if so, to what degree?

Personally I'd be very happy, in fact ecstatic, with this scenario and I wouldn't be against it at all. I'd still encourage more rational thought of course, and keep a beady eye on things.

I just realised this may well be a loaded/obvious question! Oh well, discussion welcome
