Yeah, "anti" is probably the wrong way to phrase it. Nobody dislikes the old timeline or thinks it's "bad." Hell, I've written over twenty books and stories set in the old timeline--with more on the way. And I'll be rewatching my favorite Trek movies and episodes for the rest of my life.
Here's the thing, though: Accepting a new, revamped version of an old classic doesn't mean you're rejecting or attacking the previous version. It just means you recognize that times change and beloved characters and series tend to get reworked every generation or so. Trek is no exception.
To cite another example, I enjoyed the 1990's MUMMY movies with Brendan Fraser, but that doesn't mean I stopped liking the original b/w MUMMY movies I watched as a kid. And yet I hardly expect Universal to ever return to the old 1940s "timeline."
(Just wait. When Universal
does get around to rebooting THE MUMMY again, younger fans are going to complain because it's not set in the continuity of the "classic" Brendan Fraser movies.

)
Trek is not an encyclopedia, full of immutable facts. It's a work of fiction, about an imaginary universe, to be toyed with and tweaked as necessary.
