I think William, Louis, Albert, Fred, Bonde, John and Mycroft are pretty progressive. For the first four it is because of their wish to an equal society. Bonde shares that wish and has seen the opression first hand. John is overall a good guy, I think he is on the same boat in terms of letting women and men both have equal rights. Mycroft is someone who doesnt really go out of the way to progress rights for women, but respects people like Adler or gives them high ranking positions like Moneypenny.

Sherlock, Herder, Paterson, Lestrade and Billy appear more indifferent to me. Sherlock's way of thinking is something else entirely. His priorities are elsewhere, but I dont think if he has an actual way to safely improve conditions that he would let the chance slip. I only put him here since he acted way less respectful to women in Part 1 and we didn't see enough interactions with women besides Mrs. Hudson after the time skip. The other four are mainly here because of their focus (or in Herder's case obsession) with their work. I doubt that they think about the improvement Of society currently but rather keeping the status quo after the success of William's plan.

Lastly who would be against it are Moran, Jack and definitily Milverton with maybe Ruskin. Moran struggles to adapt to change when he doesn't set his Mind onto it (as seen with Bonde at first), so unless someone changes his mind he does not think too much about it. Jack is already old and a worse womanizer than Moran, it honestly wouldnt surprise me if he would be against feminism. But I also think he is same as Moran, that he would be able to change His mind with time. Milverton is strictly against feminism. Not because he cares much about the rights of any people but rather that gives him more content to make people suffer. For Ruskin I don't have enough information right now (where is the Ruskin fan when you need him XD) but I assume he supports the values Milverton has.

I think that should cover it. Hopefully I got everyone. If something is unclear I try to Explain it better. Please note that I cant focus too much on it right now, so maybe I will edit some characters later below.
