who do you mean with pagans? It's an exonym so do you mean everyone who is not a christian? Because that is an easy bar to pas, since history has been long and religions have been many. Did you have a specific culture in mind?

Edit: The point I wanted to get to, is that if we start looking around at historical cultural/religious practices around the world, it won't take you long to find pretty questionable practices (from a contemporary humanist perspective) including all of the things you mentioned both in and outside of Christianity

Edit: You know what, you probably already know all of this, I guess the word pagans just tripped me up. Have a good night haha.
