There is no such thing as "true" Trek. I'm an old-school TOS partisan myself, but that doesn't mean I didn't watch all of later shows when they were on the air. (And have fun writing books based on most of them.)
And if somebody grows up on the Next Generation or NuTrek instead. I'm not going to tell them that "my" Trek is the only "real" Trek.
Trek is not a religion, nor should it be treated as such.
