I suppose pro- or anti-religion isn't completely orthogonal to left vs right politics. Support for a dominant religion is more likely to be found on the right, as a means of social control.
A forum could be seen as left-leaning simply by having a policy that all contributors are equal and should be treated with respect. Desire for equality (of wealth and power) is pretty much the defining left-wing characteristic.
