I wash almost everything else. I figure if my stuff cannot withstand my washing machine I don't want them.
Damn right. Garments that can't stand up to machine washing deserve to die. It's Laundry Darwinism!
I also don't believe in segregating my laundry. I just throw the white things and colored things in one big washload and let the clothes sort it out for themselves.
I very much agree with everything in your post.
My mom never separated out whites and colors either, so maybe I'm just used to the "dingy" white as the other poster put it. Though I hardly own anything white at all, almost all of my clothing is purple.
