I mean, sure? I know about “gook” and the timing does seem to work for your theory. I don’t think the connection is as obvious as you do. I don’t see sources for that part of it. A lot of other slurs are very thoroughly documented, including “gook” as a standalone. But if people find it offensive, easy enough to stop using it.

I want to thank you genuinely for making the point but also you’re being pretty rude so I think I’m not going to continue with this discussion.
