Don't rly care about the extreme get-up; as long as it isn't nudity or something vulgar, it wouldn't impact my actions tbh.
I'd be more concerned about the content of the book/what's being promoted to my kids.
Nah, I don't think it would. Besides, they need to get used to sharing a world with people who may not share their values/way of thinking. It could be a good opportunity for a life lesson xDThe book is normal, but you dont think the persons get up would influence your kids?
