I quoted this below but in case that post was obscure, what part of “Social justice is more important than being the sparkling diamond . . . Building a better industry . . . is more important than putting money in my pockets" do you find hard to understand? Seriously, she has written quite a lot, well before this. You don't have to agree with her approach (she's not asking you to btw) and it may not resonate for you* but I really don't understand what's unclear.
ETA: (a footnote) *elsewhere, you said "aside from everything else, many people might feel that to leave Broadway entirely for a reason like this, rather than sticking around and trying to help make things better. is the least helpful and worst possible choice." Could be. Certainly an opinion you are entitled to express. But history is overflowing with people who achieved things by pursuing unpopular approaches.
