Honestly, I accept Sarada as being an Uchiha. It's not as if she has brought any shame to the name or anything like that. The ONLY thing that fans have against her is the sole fact that her mother is Sakura, who herself outclasses every ninja other than Naruto and Sasuke, who are literally God-tier, and the other Kage, whom Sakura could likely hold her ground against for a significant period of time.
As for the whole Uchiha thing in general, I strongly feel that Kishimoto did Sasuke a huge disservice by having him marry Sakura and have only a single child. Sasuke's ENTIRE story revolved around avenging and restoring his clan. And considering that Sasuke is the sole surviving pure-blooded Uchiha, there would be no way to do so without resorting to certain measures. And even if those measures were taken, it would require several repeats to regain what could be "pure-blood" status.
