Gene Roddenberry doesn't own Star Trek. He never owned Star Trek. And he has been dead for more than 20 years.
Several times more Star Trek has been produced without his input as was produced with his input.
And lots of the things he did do were crap anyway.
So again. Who cares what Roddenberry thought?
And religion actually causing wars is way overstated. Lots of the so called "religious wars" were fought for purely secular reasons with religious justifications tacked on later to give the conflict the veneer of moral legitimacy.
