Yes, but not because I want it to.
We are entering an age where non-religious people are gaining number at a high.rate as
@Skwim has pointed out with his data. It may continue this way for another 10 years or so I suspect. But then it will plateau out, and begin to trend back down, as religious influence will gain numbers and with that, yes more influence and power.
Now I know what your thinking. That this is something I would want as a religious person, but that is not true. I do no wish to live under a theocracy. Even as a Christian I cannot live up to the standards of purity that a theocracy would no doubt put in place.
