I’m surprised to hear that any of these things are ‘white’ things, because all my friends of all races taste with the spoon while they are cooking- if it is for immediate family only. None of us would do this when cooking for company. Ditto the washcloth thing- I lived in a dorm for 4 years, and women of all races did (and did not) use washcloths- no link there. As for the toilet seats, well, that is just disgusting and NO ONE I know of any race admits to sitting on public toilet seats. Maybe this is more of a regional thing than racial thing.
