Indeed so (and I'm sure you are aware that 'theory' has a different meaning when used in science).
Would you be happy to have churches forced to read out a statement that god may or may not be real and that other belief systems are available?
I think people who attend church know there are other belief systems so it probably isn't necessary. But if it would make you feel more comfortable, it's fine with me. My belief in God is strong enough to withstand challenges. Can you say the same for your belief in evolution?
