There's really a big disconnect there.
FOX controls the Marvel mutants, so Whedon is going to have to come up with another origin for Wanda and Pietro. As others have speculated, he'll probably lump them in with the Inhumans and have the whole lot of them be mutated through Alien intervention. But even if mutants could be introduced into the MCU, they wouldn't necessarily have to be hated by society. Their existence could be unknown to the general populace.
