Interesting that you link to an article that has no issues with the word “tinker”.

Yes, it is, and 37 years later, it is no longer acceptable to use such terms.

On the contrary, it seems more acceptable now than 37 years ago - the “unacceptable” meaning that was already residual then (and not mentioned in the article at all!) is even more irrelevant today.

So you believe the slur is no longer used or something?

I think it's used less than 37 years ago in that sense - and it was not much of an issue back then (at least in the US, that article doesn't mention that tinker could be considered offensive while it talks about 'wetbacks').

You believe the slur is used now more than 37 years ago or something?
