To add one more category where diversity has become "an issue" and sparked backlash - live theater, especially "classics" like Shakespeare. I lived for a number of years in the hometown of the Oregon Shakespeare Festival (OSF), and saw quite a few plays during those years. OSF has been pushing the envelope to various degrees for some decades now, both in terms of casting and context for the Bard's plays, in riffing on them, and in producing contemporary plays that might, or are actually intended to, make the average -ist/-phobe unhappy and uncomfortable. A good portion of OSF regular customers think it's great and about time. But there are also plenty who don't like, for example, non-white and/or non-straight people acting in Shakespeare plays, or casting against the Bard's gender roles, or all-female casts, or all-queer casts, and so on (rather ironic, given how much cross-dressing there is in Shakespeare plays and how back in his day men played all the female roles in drag). Also plenty who don't like plays that raise race/gender/sexual orientation/colonization-oppression/etc. issues. I would hear them in the crowd as a show was letting out, or at a restaurant, or just walking through the park, complaining...
