Did you find sources and make the edit? Or just assume it would be rejected?

In my experience, the vast majority of my edits were accepted when properly sourced, especially on esoteric topics like this. Yes, there are exceptions and bad apples in the community. Those get a all the attention and media coverage but I've only encountered them on heavily edited and visited pages, not the more rare academic or historic pages. While it's anecdotal, I just checked and I've clocked nearly 800 edits in the past decade.
