Not sure that word means what you think it means. It's a Game of Thrones conversion mod. Elves, cat-people and lizardfolk don't really have any place in that world.
Sure it does. Someone essentially telling me "I removed 6 out of the 10 races in this world because I don't like them" sounds creepy to me. Especially when you fail to specify the mod used (which you've done now, but the initial creepiness still stands). It makes more sense now that you've clarified the mod you're using. A total conversion mod like that would have to eliminate certain things in the game to make it fit the new world and lore it's being turned into, but the vagaries of the original post do sound creepy.
Anyway, you're more than free to do what you want to do. If you want to remove the more interesting races of Skyrim and replace them with boring old humans, that's your business.
I'll have to look into this Game of Thrones mod. It sounds like it'll make the game completely unrecognizable.
