If you're treating two people equally, and giving them both $100, but one of them's a billionaire and one of them is below the poverty line, that's not admirable, because the effect of your equal treatment of them is disproportionate. Equal treatment regardless of any other concern is just as hostile and dystopian as outright racism, sexism or classism. Remember the cartoon of the people behind the fence? To be equitable means that you shouldn't treat people as though they were all identical in every way, because people are diverse. Yes, you should go out of your way to be inclusive of some people who if all else were equal wouldn't otherwise be included.
