I'm 43. I grew up on TOS, and I didn't start watching TNG until the 3rd season. My favorite is DS9, and I've come to appreciate what ENT could
I don't mind new stories about young Kirk, but I think the alternative canon
is stupid. Through many franchises and films, Star Trek developed a sense of history and memory that is difficult to build and difficult to replace. Not only is that difficult to replace, I doubt that anyone involved in the new Trek movies has any real desire to do so. Knowing now how Trek will develop, I would definitely protest similar "reboots," particularly to something like Tolkien's Middle Earth.
BTW, the moralizing didn't begin with Picard: Kirk could preach with the best of them.
