segregated laundry

Does the laundry care that I separate by white, reds and darks? If so will it riot? Is that why my stains wont come out?

Is bleach a weapon of mass destruction?

What about pinks and tans and greys? Do they feel like they dont belong anywhere? not enough color to be dark, but too much to be white?

If reds taint the whites pink does it become a sneeches with no star or star issue if I reclaim the whites with color remover?
