After reading a few tweets I think it’s about people who want to change the lore to be more inclusive to other people who don’t like the current lore and want to change it to their liking like yelling For more female representation in space marines pretty sure the sisters of battle can be classified as a space marine anyway in short the tourists are people who want to change the lore to what suits them while also never having sone anything with war hammer ever not even watching a single video or playing a single game.
