This does not look like a slur: https://en.wikipedia.org/wiki/Tinker https://www.dictionary.com/browse/tinker

There's also rather significant modern use of "tinker": https://en.wikipedia.org/wiki/Tinker_(disambiguation)

It appears that you're getting stuck on "tinkers", which is mentioned in the above disambiguation page:

> Tinkers, an alternate (and often pejorative) name

Anyway, language is malleable and changes. In this case, I will again emphasize "get a life."
