The whole capitalization of pronouns thing was pretty much entirely made up around the 19th century anyway (as well as the capitalizing the word “Lord”, which the King James version invented outright), so you can argue that protestant churches are following a woke plot to change the pronouns of the christian god as well.
I don’t know of any graphical tools that let you do this, but generally, if you want to search for specific terms/times/commands or anything of that sort, piping journalctl into grep (and optionally grep into less) is pretty effective at finding stuff.
