Can we stop with the tangents and go back to how this is a huge "you don't exist" to all mixed-race people? (which includes the whole Latino population?)
Sure. But they aren't removing mixed-race people from the game.
They seem to be removing mixed-race as separate game-races, and they are ceasing to refer to them as "half-X". So, "half-elves" will not be a separate character race you can choose.
But, you'll be able to make a character that has an elf and a human as parents. The first playtest packet months ago already had rules for making a character of mixed parentage. You could have a character of dwarf and elf parents, for example. I expect something similar will exist in the final ruleset.
What they had didn't make mixed-parentage a source of mechanical differences or advantage. I've seen arguments for and against that take, but either way, the assertion they are saying people of mixed-parentage don't exist seems to be false.
