This is no argument on a fedi thread
I saw someone getting mad at spell check about this and talking about it in real life years ago
If you type White people it changes it to white people but if you type jewish people it changes it to Jewish people
Now white as a color might be lower case but
if you type Gentile it changes it to gentile but if you type jew it changes it to Jew
christian is not automatically changed to Christian even though Christian as a name is a proper noun and if the Jew religion should be upper case then the Christian religion should be upper case if religions are upper case
