I guess the best comparison would be, if you have stuff all over your clothes, you'd probably shake the clothes off before putting them in the washer.

EG, I use the 'weed wacker' to cut up stuff, or I am racking leaves, I get pants with plant debris on them. I tend to shake them off first.

That'd be the equivalent of scraping your dishes, not rinsing them

Well, sorta. I find it easier to rince small stuff off, and that doesn't work with fabric really, but your point is fair.

I don't generally have food waste on my clothes though.

you must not have young kids. Food gets everywhere for a while when they are learning to eat.
