I think Discovery is making Enterprise's impact on the fan base look tame in comparison.
It will all fade once the show gets started. If people like it they will figure out how to make all fit. Whether it's prime or 3rd timeline. Whether it's fun hour of action adventure or some new edgy show that pushes the envelope.
If people don't like it they will simply move on to other shows they like and maybe be kind of sad or angry that Trek is no longer good but that is about it. Some might hate watch but that is whole different thing and something I think everyone does from time to time. I do that anytime I do a Trek marathon because I am someone who doesn't even skip the bad episodes. Feels wrong to me and naturally I have seen the "Star Wars" prequels way to much. Almost like self torture at times.
