I understand that the elephant in the room -- or aboard the starship -- in this case, is the non-“historical” production design.
We also have some counter-evidence about faithfulness, to cheer up old fans: the communicator and tricorder designs look familiar, so there's that to consider.
I try not to get overly upset about things before I have all the information about them, and I think that's a good mantra for fans at this point.
I am fine with a new design, given how often Starfleet uniforms change, apparently, at the drop of a hat.
They took one look at Finn in The Force Awakens, or an Asian Captain in Discovery, assume a political agenda they don't agree with, and don’t wait to judge on the merits.
Instead they instantly assign a pejorative term (SJW).
They are so determined to gate-keep based on their own political agenda -- which they hypocritically claim isn’t political at all -- that they can’t even wait and see what Star Trek Discovery actually delivers in terms of art, drama, and character, to make a fair assessment.
