None. Absolutely positively none.
By that same token however, nobody has done "enough" to combat the problems we as a country, as a world face.
No race, creed, color, religion, sexuality, nobody, not a single soul can say "Welp, I did my part, it's someone else's problem now." If that were the case, wouldn't we not even be having this conversation now? Have some done more than others? Absolutely. Is that fair? No. Does it change the reality? Not a bit. That said, it shouldn't be the responsibility of one group or another (again, draw the "lines" how you will) to do one single iota more than anyone else. It's not a minority problem. It's not a white problem. It's not an ally problem. It's just a fucking problem and saying "that's not my job" isn't going to do a damn thing to fix it.
As a corollary, I'll use my office as an example. There's 5 of us here with one collective job-- to help our client base and grow the business. Within my group here, I have the gamut of socioeconomic categories. Different generations, different races, different religions, different sexuality, different life experiences. My first order of business when I took over was to say "that's not my job" is a 1-way ticket out of my office. We're now the top performing unit in the company. But we're not perfect and we haven't done enough. Every single day we leave opportunity behind. We can never leave here and say "Welp, I did my part." So every day we'll continue to strive to do better than we did yesterday.
