Actually, it is not people's beliefs that are being mocked, just the idea that a particular religious myth (Intelligent Design) should be given an equal amount of respect and teaching time in science classrooms to evidence-based theories of how we got to exist. That
is the true irony; that the people accusing us of all sorts of things haven't even bothered to find out what we are truly about.
There are people here of all faiths and none. We do not, as far as I have been able to see, mock anyone for their beliefs. We do happily mock ideas
that aren't backed (or are even contradicted) by evidence as that is good science!
