I think the origin was 100% racist. But most people just used the words without thinking about the origin.

When I was s kid, they had racist names. It was just the name like a bicycle is called a bicycle. You just used the name. The realization came later when I was older and knew that the words can also be used as a slur.

To be fair though, Germany changed a lot since the 90s. Racism was way worse in the 90s/00s than now.

Dickmann‘s is a Brand. The general name is „Schaumkuss“ or „Schokoschaumkuss“. They had pretty racist names in the past and taste great
